Lam Research Corporation
Lam Research Corporation designs, manufactures, markets, refurbishes, and services semiconductor processing equipment used in the fabrication of integrated circuits in the United States, China, Korea, Taiwan, Japan, Southeast Asia, and Europe. The company offers ALTUS systems to deposit conformal or selective films for tungsten or molybdenum metallization applications; SABRE electrochemical deposition products for copper interconnect transition, which support copper damascene manufacturing; Striker single-wafer atomic layer deposition products for dielectric film solutions; and VECTOR plasma-enhanced chemical vapor deposition (CVD) products. It also provides Akara, a conductor etch system designed to enhance etch precision, selectivity, and defect control; Argos, Prevos, and Selis, which are selective etch systems used in the fabrication of advanced logic and memory devices that require precise control at nanoscale dimensions; Flex for dielectric etch applications; Vantex, a dielectric etch system that provides RF technology and repeatable wafer-to-wafer performance enabled by Equipment Intelligence solutions; Kiyo for conductor etch applications; Syndion for deep silicon etch; and Versys metal products for metal etch processes. In addition, the company offers Coronus bevel clean products to enhance die yield and Da Vinci, DV-Prime, EOS, and SP series products to address various wafer cleaning applications. Further, it provides Reliant deposition, etch, and clean products; Sense.i platform products; and customer service, spares, and upgrades. Lam Research Corporation was incorporated in 1980 and is headquartered in Fremont, California.
What does it do?
Lam Research makes the machines that build computer chips. Think of it this way: before a chip can go into your iPhone or laptop, it has to be carved and layered with microscopic precision — Lam makes the equipment that does that layering and etching. Their tools are used in the factories of companies like Samsung, TSMC, and Intel. Without Lam's machines, modern chips simply cannot be made.
The world is in a chip-building arms race — driven by AI, electric vehicles, and smartphones — and every new fab (chip factory) that gets built needs Lam's equipment to operate. Lam sits at a chokepoint: you can't build leading-edge chips without advanced etching and deposition tools, and Lam is one of only a handful of companies on earth that can supply them. That makes it one of the most strategically important companies in the entire tech supply chain right now.
How does it make money?
Lam makes money in two main ways: selling new equipment to chip manufacturers, and servicing the equipment already installed in factories around the world. Equipment sales drove the bulk of its $18.4 billion in revenue last year, up sharply from $14.9 billion the prior year — a 23% jump. The service and spare parts business is particularly valuable because it's recurring, meaning customers keep paying year after year to keep machines running. Net income came in at $5.4 billion, which is a healthy profit margin of roughly 29 cents on every dollar of revenue.
Why do investors care?
The AI boom is pushing chip companies to spend billions expanding their factories, and that spending flows directly to Lam. Every time TSMC or Samsung announces a new fab, Lam is typically one of the first calls they make. The longer-term growth story is tied to a technology shift called gate-all-around transistors and 3D NAND memory — both of which require more of Lam's specific tools per chip than older designs did. For the bull case to play out, chip capex (factory investment spending) needs to keep rising and Lam needs to hold its dominant market share in etch and deposition.
