Where is Lam Research headquartered?

Lam Research has been headquartered in Fremont, California since 1987, when the company relocated from its original Santa Clara location during its first major growth phase. The Fremont campus at 4650 Cushing Parkway is home to the C-suite, all corporate functions, primary R&D laboratories (including the Dr. Richard A. Gottscho Laboratory opened in 2016), and key manufacturing and assembly operations. The main switchboard is +1-510-572-0200.

Fremont is strategically positioned in the San Francisco Bay Area's semiconductor corridor, 30 miles southeast of San Francisco and accessible to the deep talent ecosystem of UC Berkeley, Stanford, and Silicon Valley. The adjacent Livermore, California campus serves as an additional manufacturing and advanced engineering site. Together, the Fremont and Livermore campuses form Lam's global R&D and executive nerve center — all enterprise procurement and technology buying decisions flow through Fremont.

In North America, Lam operates manufacturing campuses in Tualatin and Sherwood, Oregon (opened 2002, producing etch and deposition tool components) and in Eaton and Springfield, Ohio — geographic diversification that reduces California earthquake and logistics concentration risk. A major manufacturing facility in Penang, Malaysia (opened 2021) and a European manufacturing and engineering center in Villach, Austria support global supply chain resilience and proximity to EU customers.

In Asia-Pacific, Lam maintains its densest field presence in the three countries housing its largest chipmaker customers: South Korea (Samsung, SK Hynix — primary offices in Hwaseong and Osan, with additional presence in Yongin); Taiwan (TSMC, Micron — Taoyuan City, Hsinchu, and 20+ offices across the island); and Japan (15+ locations concentrated in the Tokyo metro area serving Japanese chipmakers and equipment suppliers). China has 15+ field service locations across major semiconductor clusters. Lam's Bengaluru, India office serves as a growing engineering, software development, and data analytics hub. EMEA operations are anchored by logistics in the Netherlands and country offices in Germany, France, UK, Austria, and Israel.

For field sales, ABM, and account planning, Lam's buying centers cluster into three tiers. Fremont, California is the tier-one location: all C-suite, VP-level, and enterprise-platform decisions are made there, making it the right geography for executive relationship events, EBC visits, and high-stakes in-person meetings. If you sell enterprise software, cloud, ERP, or operational technology to Lam, your primary territory is the San Francisco Bay Area.

South Korea (Hwaseong/Osan, in Gyeonggi province south of Seoul) is tier two for memory-specific product and operations decisions. If you sell into Lam's supply chain, field service operations, or CSBG business, Korean time-zone coverage and Korean-language capability materially increase win rates. Taiwan (Taoyuan/Hsinchu) and Japan (Tokyo metro) form tier three: the right entry points for field service technical sales, CSBG regional ops leads, and logic/advanced packaging product discussions. SEMICON West (San Jose, July) and SEMICON Korea (Seoul, January) are the highest-density ABM touchpoints where Lam concentrates its customer-facing presence globally.
