LAM RESEARCH CORP

Overview

Lam Research Corp. is a global semiconductor equipment company that supplies wafer fabrication equipment and related services used to manufacture integrated circuits.[1] Its customer base includes leading memory, foundry, and integrated device manufacturers, and its core product focus is in deposition, etch, and clean technologies, alongside service, spares, upgrades, and refurbishment offerings through its Customer Support Business Group.[2]+2 Lam says its products and services are designed to help customers build smaller, better-performing devices used in products such as mobile phones, PCs, servers, wearables, vehicles, and data storage systems.[1] The company frames its purpose around driving semiconductor breakthroughs that define the next generation.[2]

Incorporated in 1980 and headquartered in Fremont, California, Lam maintains facilities across Asia, Europe, and the United States, reflecting its broad international footprint.[5] International sales accounted for about 93% of total revenue in fiscal 2024, underscoring the company’s global exposure.[6] For fiscal 2024, Lam reported revenue of about $14.9 billion, and it reported approximately 18,300 full-time employees as of December 31, 2024.[7][8] [1]+7

Products & services

Lam Research’s product portfolio is centered on wafer-fabrication equipment for deposition, etch, and clean processes. In deposition, ALTUS deposits tungsten and molybdenum for contacts, vias, and wordlines and combines CVD and ALD to form highly conformal or selective films with in-situ nucleation and bulk fill in the same chamber; SABRE is used for copper electrofill in damascene interconnects and also supports cobalt deposition and advanced packaging uses such as bumps, redistribution layers, TSV filling, and wafer-level bonding; Striker is a single-wafer ALD platform for extremely thin, highly conformal dielectric films; VECTOR is a PECVD system for difficult dielectric applications with strong within-wafer and wafer-to-wafer uniformity; and SPEED is an HDP-CVD dielectric gapfill tool designed for high throughput, reliability, and large batch sizes.[9]+4

In etch, Flex is a critical dielectric etch platform with a multi-frequency, small-volume confined plasma design that enables in-situ multi-step etch and continuous plasma processing for high productivity and low defectivity; Vantex is aimed at advanced memory, especially 3D NAND high-aspect-ratio holes, trenches, contacts, and capacitor-cell structures while maintaining critical-dimension uniformity and selectivity; Kiyo is a conductor etch family using Hydra technology to improve CD uniformity and atomic-scale variability control; Syndion performs deep silicon etch for trenches, TSVs, and other high-aspect-ratio features with rapid process switching and precise depth uniformity; and Versys Metal is a metal etch platform designed for high productivity and profile uniformity. In clean, Coronus removes masks, residues, and films from wafer edges using plasma confinement technology to protect active die areas, while Da Vinci and DV-Prime are single-wafer spin wet-clean systems, EOS targets very low on-wafer defectivity and high throughput, and the SP Series provides wet clean and silicon wet etch tools for wafer-level packaging and IoT applications.[14]+8

Lam also sells a substantial set of services and lifecycle offerings through its Customer Support Business Group, including customer service, spares, upgrades, and new and refurbished non-leading-edge products across deposition, etch, and clean markets. These offerings are intended to maximize installed-tool performance, predictability, uptime, throughput, defect reduction, running-cost optimization, and product life extension; the company also offers Equipment Intelligence solutions and Reliant systems for specialty technologies and older fabs, as well as Semiverse software such as Fabtex Yield Optimizer. In fiscal 2025, systems revenue represented about 62.3% of total revenue, while customer support-related revenue and other represented about 37.7%, indicating that service and support are a meaningful part of overall performance.[23]+4 [9]+18

Geographic presence

Lam Research is headquartered in Fremont, California, and says it maintains a network of facilities across Asia, Europe, and the United States, supported by an extensive service-engineering presence in the United States, China, Europe, India, Japan, Korea, Southeast Asia, and Taiwan.[5][28] Its official locations page groups sites into Headquarters & Manufacturing, United States Offices, Asia Offices, and Europe & Middle East Offices; listed locations include Fremont and Livermore, California; Tualatin and Sherwood, Oregon; Boise, Idaho; Austin, Texas; Phoenix and Chandler, Arizona; Singapore; Hsinchu, Taiwan; Yokohama, Japan; Yongin, South Korea; Batu Kawan, Malaysia; Enschede, Netherlands; Dresden, Germany; Villach and Salzburg, Austria; and Bristol, UK.[29]

Lam reports sales by customer location across seven regions: the United States, China, Europe, Japan, Korea, Southeast Asia, and Taiwan.[30] For the year ended June 30, 2024, China accounted for 42% of revenue, followed by Korea at 19%, Taiwan at 11%, Japan at 10%, the United States at 7%, Southeast Asia at 6%, and Europe at 5%, so about 93% of revenue came from outside the United States.[31] Long-lived assets were concentrated primarily in the United States at about $1.58 billion, with additional concentrations in Southeast Asia at about $391 million and Korea at about $262 million, indicating that Lam’s operating asset base is anchored in the U.S. but extends across major Asian and European semiconductor markets.[32] [5]+5

Business segments

Lam Research reports a single reportable business segment rather than multiple named operating segments. The company says its material operating segments are aggregated into one segment focused on the manufacturing and servicing of wafer processing semiconductor manufacturing equipment, and segment performance is evaluated using segment gross margin.[33]

While it has one official reportable segment, Lam separately discloses revenue in two business categories. “Systems” revenue covers sales of new leading-edge equipment in deposition, etch, and clean markets, while “customer support-related revenue” includes customer service, spares, upgrades, and non-leading-edge equipment from the Reliant product line. In fiscal 2024, Systems revenue was $8.922 billion, or about 59.8% of total revenue, and customer support-related revenue and other was $5.984 billion, or about 40.2% of total revenue.[34]+2

Lam also describes its end-market exposure by primary market, though these are not reportable segments. For leading- and non-leading-edge equipment and upgrade revenue in fiscal 2024, Memory represented 42%, Foundry 40%, and Logic/integrated device manufacturing 18%.[37][38] [33]+5

Company history

Lam Research was founded by David K. Lam on January 20, 1980, and the company was incorporated that year.[39][5] It introduced its first product, the AutoEtch 480 single-wafer plasma etch system, in 1981, and went public on Nasdaq under the ticker LRCX in 1984.[40][41] In 1997, Lam merged with OnTrak Systems; subsequent company materials describe OnTrak as a wholly owned subsidiary and highlight its CMP cleaning products, marking an expansion beyond Lam’s original etch focus.[42][43] In 2000, Lam launched the 2300 Etch Series, which it described as the industry’s first etch product line capable of handling both 200 mm and 300 mm wafers.[44]

Lam continued broadening its process portfolio in the late 2000s by pursuing SEZ Group, announcing its intent to acquire the company in 2007 and reporting in early 2008 that the tender offer had secured 94.26% of SEZ shares and the required competition clearances.[45][46] A larger strategic milestone followed on June 4, 2012, when Lam completed its merger with Novellus Systems; company filings say the transaction expanded Lam into thin-film deposition and surface preparation.[47]+2 More recently, leadership changed in 2018 when Martin Anstice resigned and Tim Archer was appointed president and chief executive officer.[50] [5]+12
