Lam Research

Lam Research is a major semiconductor equipment manufacturer specializing in wafer fabrication equipment used in the deposition, etching, and cleaning steps of chip manufacturing. Along with Applied Materials and Tokyo Electron, Lam Research is one of the three dominant companies in semiconductor process equipment.

Lam's equipment is essential for manufacturing the advanced AI chips produced by TSMC, Samsung, and Intel. As chip architectures become increasingly complex — with 3D stacking, advanced packaging, and sub-3nm process nodes — Lam Research's precision etching and deposition tools become ever more critical.

Lam Research occupies a foundational position in the semiconductor supply chain: without its equipment, the advanced chips powering AI inference and training could not be manufactured at the required precision and scale.
