David K. Lam founded the company in 1980 in Fremont to build the first practical automated plasma etcher, replacing wet chemical etching that could not scale to finer circuit geometries.
The dry etch bet proved foundational: as chips shrank, precision plasma etching became essential, and Lam grew into the category leader through the rise of American chip manufacturing.
The 2012 Novellus acquisition for $3.3 billion added deposition and clean capabilities, and the blocked 2015 KLA-Tencor merger marked its largest strategic setback. The AI era's demand for advanced logic and HBM memory drove record fiscal 2025 revenue of approximately $18.4 billion.
