Lam Research Corporation

A maker of the machinery that fabricates silicon chips—the etch, deposition, and cleaning tools used by manufacturers like Samsung, SK hynix, Micron, and TSMC to build memory and logic semiconductors. Founded in 1980 by Dr. David K. Lam in Santa Clara, California, the company's name isn't an acronym despite jokes about "Let's All Move"—it simply honors its founder's surname. Its product families include Kiyo and Flex etch tools and ALTUS and VECTOR deposition systems.
