LAM RESEARCH CORP (LRCX)
SEC filings, insider trading & institutional ownership from EDGAR.
Lam Research Corporation, incorporated in Delaware in 1980 and headquartered in Fremont, California, is a global supplier of wafer fabrication equipment and services to the semiconductor industry, with facilities across Asia, Europe, and the United States. The company's core competencies include nanoscale manufacturing, chemistry, plasma and fluidics, and advanced systems engineering, enabling customers—leading semiconductor memory, foundry, and integrated device manufacturers (IDMs) such as Samsung Electronics and Taiwan Semiconductor Manufacturing Company, its most significant customers—to build smaller, higher-performing devices for markets including mobile phones, cloud computing, AI, 5G, IoT, and automotive applications. Lam's primary product portfolio spans deposition, etch, and clean technologies: deposition products (ALTUS®, SABRE®, SPEED®, Striker®, VECTOR® families) create metal and dielectric layers; etch products (Flex®, Vantex®, Kiyo®, Syndion®, Versys® Metal families) selectively remove materials to form chip features; and clean products (Coronus®, DV-Prime®, Da Vinci®, EOS®, SP Series) remove contaminants between manufacturing steps.
The company also serves back-end wafer-level packaging (WLP), including fan-out panel-level packaging and 3D stacking solutions for high bandwidth memory (HBM), as well as related markets like CMOS image sensors (CIS) and MEMS. Its Customer Support Business Group (CSBG) provides lifecycle services including equipment upgrades, spares, Equipment Intelligence® solutions, and the Reliant® line of new and refurbished non-leading-edge equipment. Lam invests heavily in R&D to sustain technological leadership amid rapid industry change, competing primarily against Applied Materials, ASM International, Wonik IPS, Hitachi, Tokyo Electron, Screen Holdings, and Semes across its deposition, etch, and clean markets.
The company maintains an extensive global service network across the U.S., China, Europe, India, Japan, Korea, Southeast Asia, and Taiwan, and is subject to numerous governmental regulations including export controls, trade restrictions, and environmental rules, with particular exposure to U.S.-China trade tensions and export licensing requirements affecting sales to Chinese customers. As of August 2025, Lam employed approximately 19,000 regular full-time employees globally, with over 29% engaged in research and development, and maintains ESG commitments including a goal of net zero emissions by 2050. For fiscal year 2025, ended June 29, 2025, the company continued to emphasize innovation, customer collaboration, and a broad product portfolio to address technology inflections such as 3D architecture and multiple patterning driven by demand for more powerful, cost-efficient semiconductors.
