Overview
Lam Research designs and builds equipment and provides services for making computer chips. Its products are used in front-end wafer processing, the steps that form active components and wiring on silicon wafers. Core systems cover thin film deposition, plasma etch, and wafer cleaning, which together create transistors and interconnects on a wafer. Lam Research sells new and refurbished equipment and earns revenue from service contracts and spare parts, supporting customers with maintenance and ongoing needs. Compared with competitors, the company combines a broad suite of front-end processing tools with global service offerings and a strong base among leading chip manufacturers such as IDMs, foundries, and memory suppliers. Its goal is to help semiconductor makers produce chips efficiently and reliably by supplying the equipment and services needed for wafer fabrication.
