Pdf Solutions Inc
A maker of software and analytics tools for the semiconductor industry, PDF Solutions doesn't build chips itself but supplies the data platforms—brands like Exensio, Sapience, and Cimetrix—that connect fabrication equipment, analyze manufacturing data, and help chipmakers improve production yield. It was founded in 1991 by two engineers, and despite its name, "PDF" stands for "Product Design for Manufacturing"—not the Portable Document Format file type it's often mistaken for.
