4.A. History and Development of the Company
Himax Taiwan, our predecessor, was incorporated on June 12, 2001 as a limited liability company under the laws of the ROC. On April 26, 2005, we established Himax Technologies Limited, an exempted company with limited liability under the Cayman Islands Companies Law, as a holding company to hold the shares of Himax Taiwan in connection with our reorganization and share exchange. On October 14, 2005, Himax Taiwan became our wholly owned subsidiary through a share exchange consummated pursuant to the ROC Business Mergers and Acquisitions Law through which we acquired all of the issued and outstanding shares of Himax Taiwan, and we issued ordinary shares to the shareholders of Himax Taiwan. Shareholders of Himax Taiwan received one of our ordinary shares in exchange for one Himax Taiwan common share. The share exchange was unanimously approved by shareholders of Himax Taiwan on June 10, 2005 with no dissenting shareholders and by the ROC Investment Commission on August 30, 2005 for our inbound investment in Taiwan, and on September 7, 2005 for our outbound investment outside of Taiwan. We effected this reorganization and share exchange to comply with ROC laws, which prohibit a Taiwan incorporated company not otherwise publicly listed in Taiwan from listing its shares on an overseas stock exchange. Our reorganization enables us to maintain our operations through our Taiwan subsidiary, Himax Taiwan, while allowing us to list our shares overseas through our holding company structure.

Flat Panel Display Semiconductors
Flat panel displays require different semiconductors depending upon the display technologies and the applications. Some of the most important ones include the following:
● Display Driver. The display driver receives image data from the timing controller and delivers precise analog voltages or currents to create images on the display. The major application of display driver IC is used on TFT-LCDs. Other than display drivers for TFT-LCDs, we also offer display drivers for OLED and Electronic Paper (e-paper) Displays. OLED display is getting more and more popular in recent years, starting from high-end smartphone and TV applications towards tablet, notebook and automotive, while e-paper display mimics traditional paper sheet and holds static text and images indefinitely without electricity. Detailed display driver IC specification for LCD, OLED and e-paper are different due to panel characteristics. The two main types of display drivers for a display panel are gate drivers and source drivers. Gate drivers turn on the transistor within each pixel cell on the horizontal line on the panel for data input at each row. Source drivers receive image data from the timing controller and generate voltage that is applied to the liquid crystal within each pixel cell on the vertical line on the panel for data input at each column. The combination determines the colors generated by each pixel. Typically, multiple gate drivers and source drivers are installed separately on the panel. However, for certain small and medium-sized applications, gate drivers and source drivers are integrated into a single chip due to space and cost considerations. Large-sized panels typically have higher resolution and require more display drivers than small and medium-sized panels. In addition, TDDI IC integrates both display driver and in-cell touch functions and is usually adopted by small and medium sized display applications, whereas Timing Controller feature is also embedded in TDDI.
● Timing Controller. The timing controller receives image data and converts the format for the source drivers’ input. The timing controller also generates controlling signals for gate and source drivers. Typically, the timing controller is a discrete semiconductor in TFT-LCD, OLED and e-paper panels. For certain small and medium-sized applications, however, the timing controller may be integrated with display drivers.
● Operational Amplifier. An operational amplifier supplies the reference voltage to source drivers in order to make their output voltage uniform.
● Power IC. Power ICs include certain drivers, amplifiers, DC to DC converters and other semiconductors designed to enhance power management, such as voltage regulation, voltage boosting and battery management.
● Touch Controller IC. For touch screen applications, touch controller ICs enable touch interfaces, such as capacitive touch panels, to identify, qualify and track user’s contacts with precision and sensibility. For TFT LCD panels, the touch controller may be integrated with display drivers as an in - cell TDDI solution, commonly adopted in devices including smartphones, tablets, automotive displays, and notebooks. In contrast, OLED panels typically adopt a discrete touch controller to realize touch functionality.
● Others. Flat panel displays also require multiple general purposes semiconductors such as memory, power converters and inverters.
Characteristics of the Display Driver Market
Although we operate in several distinct segments of the flat panel display semiconductor industry, our principal products are display drivers. Display drivers are critical components of flat panel displays. The display driver market has specific characteristics, including those discussed below.

Concentration of Panel Manufacturers
The global TFT-LCD panel industry consists of a small number of manufacturers, substantially all of which are based in Asia. In recent years, Korean TFT-LCD panel makers have gradually undergone restructurings to shift their technology and manufacture focus from TFT-LCD to OLED and TFT-LCD panel manufacturers, especially China-based manufacturers which have invested or are planning to invest heavily to establish, construct and ramp up additional fab capacity. The capital-intensive nature of the industry often results in TFT-LCD panel manufacturers operating at a high level of capacity utilization in order to reduce unit costs. This tends to create a temporary oversupply of panels, which reduces the average selling price of panels and puts pricing pressure on component companies including display driver companies. Moreover, the concentration of panel manufacturers permits major panel manufacturers to exert pricing pressure on display driver companies such as us. The small number of panel manufacturers exacerbates this situation as display driver companies, in addition to seeking to expand their customer base, must also focus on winning a larger percentage of such customers’ display driver requirements.
Customization Requirements
Each panel display has a unique pixel design to meet its particular requirements. To optimize the panel’s performance, display drivers have to be customized for each panel design. The most common customization requirement is for the display driver company to optimize the gamma curve of each display driver for each panel design. Display driver companies must work closely with their customers to develop semiconductors that meet their customers’ specific needs in order to optimize the performance of their products.
Mixed-Signal Design and High-Voltage CMOS Process Technology
Display drivers have specific design and manufacturing requirements that are not standard in the semiconductor industry. Some display drivers require mixed-signal design since they combine both analog and digital devices on a single semiconductor to process both analog signals and digital data. Manufacturing display drivers require high-voltage CMOS process technology operating typically at 4.5 to 24 volts for source drivers and 10 to 50 volts for gate drivers, levels of voltage which are not standard in the semiconductor industry. For display drivers, the driving voltage must be maintained under a very high degree of uniformity, which can be difficult to achieve using standard CMOS process technology. Moreover, manufacturing display drivers does not require very small-geometry semiconductor processes. Typically, the manufacturing process for large panel display drivers require geometries between 0.11 micron and 1 micron because the physical dimensions of a high-voltage device do not allow for the economical reduction in geometries below this range. We believe that there are a limited number of fabs with high-voltage CMOS process technology that are capable of high-volume manufacturing of display drivers.
Special Assembly and Testing Requirements
Manufacturing display drivers requires certain assembly and testing technologies and equipment that are not standard for other semiconductors and are offered by a limited number of providers. The assembly of display drivers typically uses either tape-automated bonding, also known as TAB, or chip-on-glass, also known as COG, technologies. Display drivers also require gold bumping, which is a process in which gold bumps are plated onto each wafer to connect the die and the processed tape, in the case of TAB packages, and the glass, in the case of COG packages. TAB may utilize tape carrier packages, also known as TCP, or chip on film, also known as COF. The type of assembly used depends on the panel manufacturer’s design, which is influenced by panel size and application and is typically determined by the panel manufacturers. Display drivers for large-sized applications typically require TAB package and, to a lesser extent, COG package types, whereas display drivers for smartphone, tablet and consumer electronics products typically require COG packages. The testing of display drivers also requires special testers that can support high-channel and high-voltage output semiconductors. Such testers are not standard in the semiconductor industry.

Supply Chain Management
The manufacturing of display drivers is complex and requires several manufacturing stages such as wafer fabrication, gold bumping, and assembly and testing, and the availability of materials such as the processed tape used in TAB packaging. We refer to these manufacturing stages and material requirements collectively as the “supply chain”. Panel manufacturers typically operate at high levels of capacity utilization and require a reliable supply of display drivers. A shortage of display drivers, or a disruption to this supply, may disrupt panel manufacturers’ operations. As a result, a company’s ability to deliver its products on a timely basis at the quality and quantity required is critical to satisfying its existing customers and winning new ones. Such supply chain management is particularly crucial to fabless display driver companies that do not have their own in-house manufacturing capacity. In the case of display drivers, supply chain management is further complicated by the high-voltage CMOS process technology and the special assembly and testing requirements that are not standard in the semiconductor industry. Access to this capacity also depends in part on display driver companies having received assurances of demand for their products since semiconductor manufacturing service providers require credible demand forecasts before allocating capacity among customers and investing to expand their capacity to support growth.
Need for Higher Level of Integration
The small form factor of smartphone, tablet, automotive and certain consumer electronics products restricts the space for components. Small and medium-sized panel applications typically require one or more source drivers, one or more gate drivers and one timing controller, which can be installed as separate semiconductors or as an integrated single-chip driver. Customers are increasingly demanding higher levels of integration in order to manufacture more compact panels, simplify the module assembly process and reduce unit costs. Display driver companies must be able to offer highly integrated chips that combine the source driver, gate driver and timing controller, as well as semiconductors such as memory, power circuit and image processors, into a single chip. Due to the size restrictions and stringent power consumption constraints of such display drivers, single-chip drivers are complex to design. For large-sized panel applications, integration is both more difficult to achieve and less important since size and weight are less of a priority. Lastly, as some of our TFT-LCD panel customers had turned to pure in-cell TDDI panel development for thinner display designs, we have developed a series of single chip touch display driver integrated circuit (TDDI) for advanced in-cell touch display panel.

Display Drivers and Timing Controllers
Display Driver Characteristics
Display drivers deliver precise analog voltages and currents that activate the pixels on panels. The following is a summary of certain display driver characteristics and their relationship to panel performance.
● Resolution and Number of Channels. Resolution refers to the number of pixels per line multiplied by the number of lines, which determines the level of fine detail within an image displayed on a panel. For example, a color display screen with 1,024 x 768 pixels has 1,024 red columns, 1,024 green columns and 1,024 blue columns for a total of 3,072 columns and 768 rows. The red, green and blue columns are commonly referred to as “RGB.” Therefore, the display drivers need to drive 3,072 column outputs and 768 row outputs. The number of display drivers required for each panel depends on the resolution of the panel and the number of channels per display driver. For example, an XGA (1,024 x 768 pixels) panel requires eight 384-channel source drivers (1,024 x 3 = 384 x 8) and three 256-channel gate drivers (768 = 256 x 3), while a full HD (1,920 x 1,080 pixels) panel requires eight 720-channel source drivers and four 270-channel gate drivers. The number of display drivers required can be reduced by using drivers with a higher number of channels. For example, a full HD panel can have six 960-channel source drivers instead of eight 720-channel source drivers. Thus, using display drivers with a higher number of channels can reduce the number of display drivers required for each panel, although display drivers with a higher number of channels typically have higher unit costs.
● Color Depth. Color depth is the number of colors that can be displayed on a screen, which is determined by the number of shades of a color, also known as gray scale, that can be shown by the panel. For example, a 6-bit source driver is capable of generating 26 x 26 x 26 = 218, or 262K colors, and similarly, an 8-bit source driver is capable of generating 16 million colors. Typically, for TFT-LCD panels currently in commercial production, 262K, 16 million and 1 billion colors are supported by 6-bit, 8-bit and 10-bit source drivers, respectively.
● Operational Voltage. A display driver operates with two voltages: the input voltage (which enables it to receive signals from the timing controller) and the output voltage (which, in the case of source drivers, is applied to liquid crystals and, in the case of gate drivers, is used to switch on the TFT device). Source drivers typically operate at input voltages from 3.3 to 1.8 volts and output voltages ranging from 4.5 to 24 volts. Gate drivers typically operate at input voltages from 3.3 to 1.8 volts and output voltages ranging from 10 to 50 volts. Lower input voltage saves power and lowers electromagnetic interference, or EMI. Output voltage may be higher or lower depending on the characteristics of the liquid crystal (or diode), in the case of source drivers, or TFT device, in the case of gate drivers.
● Gamma Curve. The relationship between the light passing through a pixel and the voltage applied to it by the source driver is nonlinear and is referred to as the “gamma curve” of the source driver. Different panel design and manufacturing processes require source drivers with different gamma curves. Display drivers need to adjust the gamma curve to fit the pixel design. Due to the materials and processes used in manufacturing, panels may contain certain imperfections which can be corrected by the gamma curve of the source driver, a process which is generally known as “gamma correction.” For certain types of liquid crystal, the gamma curves for RGB cells are significantly different and thus need to be independently corrected. Some advanced display drivers feature three independent gamma curves for RGB cells.
● Driver Interface. Driver interface refers to the connection between the timing controller and display drivers. Display drivers increasingly require higher bandwidth interface technology to address the larger data volume necessary for video images. Panels used for higher data transmission applications, such as televisions, require more advanced interface technology. The principal types of interface technologies are transistor-to-transistor logic, or TTL, reduced swing differential signaling, or RSDS, mini-low voltage differential signaling, or mini-LVDS, and point-to-point high-speed interface. Among these, RSDS, mini-LVDS and point-to-point interface were developed as low power, low noise and low amplitude methods for high-speed data transmission using fewer copper wires and resulting in lower EMI. Moreover, there are some panel manufacturers developing their proprietary point-to-point interfaces, such as embedded panel interface, or EPI, USI-T, iSP, CEDS, CHPI, CSPI and CMPI.

● Package Type. The assembly of display drivers typically uses TAB and COG package types. COF and TCP are two types of TAB packages, of which COF packages have become predominantly used in recent years. Customers typically determine the package type required according to their specific mechanical and electrical considerations. In general, display drivers for small-sized panels mainly use COG package types, whereas display drivers for large-sized panels primarily use TAB package types and, to a lesser extent, COG package types.
Large-Sized Applications
We provide source drivers, gate drivers, PMIC, P-gamma OP level shifter and timing controllers (TCON) for large-sized panels principally used in desktop monitors, notebook computers and televisions. Display drivers used in large-sized applications feature different key characteristics, depending on the end-use application. For example, the industry trend for large-sized applications is generally toward super high channel, low power consumption, low cost, thin and light form factor, touch function, higher data transmission rate and higher driving capabilities. Higher speed interface technologies are also key for 4Kx2K and 8Kx4K high-resolution TVs. Greater color depth, thermal solution, high data rate and high driving, are particularly important for advanced televisions and certain monitors.
Our large display driver IC business achieved several milestones since 2019. For example, we successfully added 12-inch fabs into the pool of our foundry capacity for our large display driver ICs to ease the capacity shortage of 8” foundry where the vast majority of large panel driver ICs are fabricated. On high-end TV, Himax outpaced peers to lead the mass production of customized high-speed point-to-point (P2P) transmission using embedded panel intra interface such as iSP, CHPI, USI-T, CMPI, CEDS and CSPI for 4K TVs and 8K TV. On gaming monitor, we have high frame rate and high driving driver to meet various resolutions needs and frame rates such as UHD 240Hz, QHD 360Hz, FHD 480Hz, etc. We also successfully developed low power consumption driver applied in low power monitor to satisfied Energy Star 8.0 and even Energy Star 9.0. Additionally, our P2P driver and TCON ICs with 13.3” FHD can meet Intel 1W project requirements.
For automotive TCONs, Himax has a dominant market share and offers a comprehensive product offerings featuring local dimming functionality, image enhancement, HDR, OSD, de-warping, to meet customers’ various needs of automotive displays We also provide gaming TCON for the new FHD 1000Hz, QHD 480Hz and UHD 240Hz gaming monitor and notebook. For high-end gaming -oriented applications, we have developed eDP 8.1G TCON to increase bandwidth. We are also developing eDP1.5 for notebooks.

Smartphone and Tablet Applications
We offer display drivers for small and medium-sized displays in smartphone and tablet applications that combine source driver, gate driver, timing controller, DC to DC circuits, and optional frame buffer into a single chip or cascades chips in various display technologies, such as TFT-LCD and OLED.
Smartphones and tablet have gained greater popularity among small and medium-sized display drivers and enjoyed high growth in recent years. This has also contributed to increased demand for larger size and higher resolution smartphone displays. In 2016, Himax developed a series of single chip touch display driver integrated circuit (TDDI) for advanced in-cell touch display panel. Himax started the shipments of in-cell TDDI for some smartphones in 2016 and extended TDDI solution to tablet application in 2017. In-cell TDDI, featuring thinner display, slimmer border, and better visual quality, has been getting popular, so we re-invented a new generation of TDDIs supporting COG and COF for 18:9 or wider aspect ratio with interlaced output pins, which makes the bottom border of the in-cell touch display even smaller to gain higher display to body ratio. Our FHD+ and HD+ TDDI successfully gained design-wins with a few leading Korean and Chinese smartphone brands and panel makers. We started small volume shipments in the first half of 2018 with accelerating volume starting in the second half of 2018 into 2019 and beyond. Starting in 2020, Himax extended our product offerings with high frame rate TDDI solution and has started shipping to top-tier smartphone OEMs.

CMOS Image Sensor Products
The CMOS image sensor products are developed by our subsidiary, Himax Imaging. The products were designed firstly for camera-equipped mobile devices, such as mobile phones, tablets and notebook computers, with a focus on low light image and video quality. Although it seems relatively challenging for us to gain significant market share in conventional RGB camera, we do think there are various interesting and different applications in imaging. Based on the technologies and IP we developed, on top of legacy products for laptop and multimedia we have been supplying, our product lines have been expanded to cover three domains: ultralow power computer vision- Always-On Sensor (“AoS”), Near Infrared (“NIR”) sensor, and big pixel BSI sensors in automotive and surveillance. In 2019, we further prioritized our focus on ultralow power computer vision- Always-On Sensor (“AoS”) as the demand for battery-powered smart device with AI intelligent sensing is rapidly growing. Together with the technologies we already developed, such as Near Infrared (“NIR”) sensor, we can provide our customers the best integrated solutions for several specific domains. In May 2024, we announced a strategic investment in Obsidian Sensors, Inc. ("Obsidian"), a San Diego-based thermal imaging sensor solution manufacturer. The investment was motivated by the potential of Obsidian’s proprietary and revolutionary high-resolution thermal sensors to establish a market position through low-cost, high-volume production capabilities. The investment positions us at the forefront of machine vision AI applications, delivering high effectiveness particularly in harsh environments and completely dark scenarios. In addition, through several strategic investments, including those in thermal imaging sensing technology, Himax has strengthened its sensor portfolio and expanded its technological capabilities. Because thermal sensing does not capture personally identifiable visual data, it helps address privacy concerns. Together, these capabilities enable Himax to deliver highly integrated solutions across multiple domains.
In specific domains, such as battery-powered surveillance cameras, doorbell cameras, and door-lock applications, customers require not just an ultralow power sensor for sensing or pre-rolling functions, but also high-resolution video for end-users after an event occurs. Himax Imaging addresses these needs by providing a 1/3” 4MP sensor with a 1:1 aspect ratio. This sensor features a 2048x2048 resolution tailored for doorbell and door-lock cameras, delivering a broad Field of View (FOV) in both horizontal and vertical directions. This capability allows users to observe a visitor's entire body, even when they stand very close to the camera. Himax Imaging can offer a variety of these 2-in-1 sensors, combining high-resolution video capabilities with low-resolution ultralow power imaging for the surveillance market.

Core Technologies and Know-How
Driving System Technology. Through our collaboration with Panel Manufacturers, we have developed extensive knowledge of circuit design, TFT-LCD/OLED driving systems, high-voltage CMOS processes and display systems, all of which are important to the design of high-performance TFT-LCD/OLED display drivers. Our engineers have in-depth knowledge of the driving system technology, which is the architecture for the interaction between the source driver, gate driver, timing controller and power systems as well as other passive components. We believe that our understanding of the entire driving system has strengthened our design capabilities. Our engineers are highly skilled in designing power efficient and compact display drivers that enhance the performance of TFT-LCD/OLED. We are leveraging our know-how of display drivers and driving system technology to develop display drivers for panels utilizing other technologies such as next generation OLED and electronic paper displays.
High-Voltage CMOS Circuit Design. Unlike most other semiconductors, TFT-LCD display drivers require a high output voltage of 3.3 to 50 volts. We have developed circuit design technologies using a high-voltage CMOS process that enables us to produce high-yield, reliable and compact drivers for high-volume applications. Moreover, our technologies enable us to keep the driving voltage at very high uniformity, which can be difficult to achieve when using standard CMOS process technology.
High-Bandwidth Interfaces. In addition to high-voltage circuit design, TFT-LCD display drivers require high bandwidth transmission for video signals. We have applied several high-speed interfaces, including transistor-transistor logic (“TTL”), Reduced Swing Differential Signaling (“RSDS”), mini low-voltage differential signaling (“LVDS”), dual-edge TTL (“DETTL”), turbo Reduced Swing Differential Signaling (“RSDS”), Mobile Industry Processor Interface (“MIPI”) and other customized interfaces in our display drivers. Moreover, we are developing additional driver interfaces for special applications with optimized speed, lower EMI and higher system stability.
Die Shrink and Low Power Technologies. Our engineers are highly skilled in employing their knowledge of driving technology and high-voltage CMOS circuit design to shrink the die size of our display drivers while leveraging their understanding of driving technology and panel characteristics to design display drivers with low power consumption. Die size is an important consideration for applications with size constraints. Smaller die size also reduces the cost of the chip. Lower power consumption is important for many portable devices such as notebook computers, smartphone, tablet and consumer electronics products.
WiseEye Ultralow Power AI Sensing Technologies. These technologies are composed by an AoS sensor, an edge AI ASIC processor and computer-vision AI algorithm, all operated in ultralow power mode. Our industrial first AoS CMOS image sensor features ultralow power and low latency back-illuminated solution for always on, intelligent visual sensing applications. With Himax’s exceptional low power know-how and ASIC implementation technologies, our WiseEye AI image processor featured different power domain and mode management schemes, together with advanced image processing hardwired accelerators to construct different operating modes in balancing processor performance and power consumptions. The seamless and proprietary interface between our AoS sensor and AI processor ensure the efficient and fast-response sensor data transmission and wake-up mechanism operating in ultralow power mode.

We also rely largely on third-party suppliers of processed tape used in TAB packaging. We engage foundries with high-voltage CMOS process technology for our display drivers and engage assembly and testing houses that specialize in TAB and COG packages, thereby taking advantage of the economies of scale and the specialization of such semiconductor manufacturing service providers. Our primarily fabless model enables us to capture certain financial and operational benefits, including reduced manufacturing personnel, capital expenditures, fixed assets and fixed costs. It also gives us the flexibility to use the technology and service providers that are the most suitable for any given product. Despite our reliance on outsourcing for CP testing, we have made investments in internal capabilities for test program development, engineering testing, debugging capability and manufacturing support since 2022.
We operate a fab under Himax Display primarily for performing manufacturing processes for our LCoS microdisplays. Moreover, we have established an in-house WLO facility under Himax Taiwan for the key process of our wafer level optics products, which started small-scale shipments from December 2009 and commenced mass shipment to anchor customer from 2017 onwards. We began construction of our new building, Fab 2, in March 2017, located nearby the current headquarters to house additional WLO capacity, the new active alignment equipment needed for our 3D sensing business and to provide extra office space.

Manufacturing Stages
The diagram below sets forth the various stages in manufacturing display drivers according to the two different types of assembly utilized: TAB or COG. The assembly type depends primarily on the application and design of the panel and is determined by our customers.
Wafer Fabrication: Based on our design, the foundry provides us with fabricated wafers. Each fabricated wafer contains many chips, each known as a die.
Gold Bumping: After the wafers are fabricated, they are delivered to gold bumping houses where gold bumps are plated on each wafer. The gold bumping process uses thin film metal deposition, photolithography and electrical plating technologies. The gold bumps are plated onto each wafer to connect the die to the processed tape, in the case of TAB package, or the glass, in the case of COG package.
Chip Probe Testing: Each die is electrically tested, or probed, for defects. Dies that fail this test are discarded.
Assembly and Testing: Our display drivers use two types of assembly technology: TAB or COG. Display drivers for large-sized applications typically require TAB package types and to a lesser extent COG package types, whereas display drivers for smartphone, tablet and consumer electronics products typically require COG package types.
48
Table of Contents
TAB Assembly
We use two types of TAB technologies: TCP and COF. TCP and COF packages are both made of processed tape that is typically 35mm or 48mm wide, plated with copper foil and has a circuit formed within it. TCP and COF packages differ, however, in terms of their chip connections. With TCP packages, a hole is punched through the processed tape in the area of the chip, which is connected to a flying lead made of copper. By contrast, with COF packages, the lead is mounted directly on the processed tape and there is no flying lead. In recent years, COF packages have become predominantly used in TAB technology.
● Inner-Lead Bonding: The TCP and COF assembly process involves grinding the bumped wafers into their required thickness and cutting the wafers into individual dies, or chips. An inner lead bonder machine connects the chip to the printed circuit processed tape and the package is sealed with resin at high temperatures.
● Final Testing: The assembled display drivers are tested to ensure that they meet performance specifications. Testing takes place on specialized equipment using software customized for each product.
COG Assembly
COG assembly connects display drivers directly to LCD panels without the need for processed tape. COG assembly involves grinding the tested wafers into their required thickness and cutting the wafers into individual dies, or chips. Each individual die is picked and placed into a chip tray and is then visually or auto-inspected for defects. The dies are packed within a tray in an aluminum bag after completion of the inspection process.
Quality Assurance
We maintain a comprehensive quality assurance system. Using a variety of methods, from conducting rigorous simulations during the circuit design process to evaluating supplier performance at various stages of our products’ manufacturing process, we seek to bring about improvements and achieve customer satisfaction. In addition to monitoring customer satisfaction through regular reviews, we implement extensive supplier quality controls so that the products we outsource achieve our high standards. Prior to engaging a third party as our supplier, we perform a series of audits on their operations, and upon engagement, we hold frequent quality assurance meetings with our suppliers to evaluate such factors as product quality, production costs, technological sophistication and timely delivery.
In November 2002, we received ISO 9001 certification, which was renewed in March 2024 and will expire in March 2027. In February 2006, we received ISO 14001 certification, which was renewed in December 2023 and will expire in December 2026. In addition, in March 2007, we received IECQ QC 080000 certification, which was renewed in February 2025 and will expire in March 2028.

4.D. Property, Plants and Equipment
Our corporate headquarters are located at a 22,172 square meter facility within the Tree Valley Industrial Park in Tainan, Taiwan. We began construction of our new building, Fab 2, in March 2017, located nearby the current headquarters. The newly completed building, located at a 42,619 square meter facility, houses additional WLO capacity, the new active alignment equipment needed for our 3D sensing business and provides extra office space. The facilities house our research and development, engineering, sales and marketing, operations and general administrative staff.
We also lease office space in Taipei and Hsinchu, Taiwan; Suzhou, Shenzhen, Foshan, Beijing, Shanghai, Ningbo, Wuhan, Hefei, Xiamen, Chongqing, Fuqing, China; Asan-si and Bundang-gu, South Korea; and Irvine and San Jose, California and Minneapolis, Minnesota, USA. The lease contracts may be renewed upon expiration.
We have established an in-house WLO facility under Himax Taiwan for the key process of our products. The facility occupies 1,171 square meters of floor space in a building leased from Innolux, which was already produced and shipped over 50 million optics to Tier-1 customer since 2010. However, the building lease was terminated early at the end of January 2024, and we relocated the WLO facility to our Fab 2. We have also expanded certain facilities for LCoS and WLO products to accommodate new customers and new applications located at our headquarters in Tainan, Taiwan. To build up test program development, engineering testing, debugging capability and manufacturing support, we have established under Himax Taiwan an in-house CP test facility from 2022.
