Lam Research Corporation (Lam Research) is a supplier of wafer fabrication equipment and services to the semiconductor industry. The Company's products are used primarily in front-end wafer processing, which involves the steps that create the active components of a device and their wiring. It also addresses processes for back-end wafer-level packaging (WLP). In addition, its products are offered for related markets that rely on semiconductor processes and require production-proven manufacturing capability, such as micro-electromechanical systems (MEMS). Its thin film deposition systems form a device's sub-microscopic layers of conducting (metal) or insulating (dielectric) materials. It is a provider of plasma etch, a process step that selectively removes materials from the wafer to create the features and patterns of a device. Its wet spin clean and plasma-based bevel clean products remove particles, residues and film from the wafer surface before or after adjacent processes.
