Revenue model

Transactional equipment sales (deposition, etch, and clean systems) plus aftermarket customer support services through the Customer Support Business Group. FY2025 total revenue was $18.4 billion, with gross margin of 48.7% (10-K, filed 2025-08-11).

Products and services

Wafer fabrication equipment spanning three process categories: deposition, etch, and clean. Etch products include the Kiyo product family (conductor etch, featuring proprietary Hydra technology for CD uniformity) and the Syndion product family (deep silicon etch for TSVs, CMOS image sensors, power devices, and HBM advanced packaging). The Customer Support Business Group provides aftermarket services and products to maintain installed equipment performance.

Customers and end markets

Semiconductor manufacturers (chipmakers) across memory and non-memory markets. End demand is driven by cloud computing, artificial intelligence, 5G, and the Internet of Things. The filing does not disclose specific customer names or concentration percentages.

Value-chain role

Equipment supplier to semiconductor fabricators, sitting upstream of chip production. Lam sells the machines and services that chipmakers use to deposit, etch, and clean materials on wafers during the fabrication process.

Geographic exposure

Global, with facilities across Asia, Europe, and the United States. The filing notes that U.S. export controls restrict sales of certain equipment and spare parts to customers in China, including entity-listed customers, which affects the China portion of the business (10-K, filed 2025-08-11).
