LAM RESEARCH CORP (LRCX)
SEC filings, insider trading & institutional ownership from EDGAR.
Lam Research Corporation, incorporated in 1980 as a Delaware corporation, is a global supplier of wafer fabrication equipment and services to the semiconductor industry. Its core competencies include nanoscale manufacturing enablement, chemistry, plasma and fluidics, and advanced systems engineering. The company integrates hardware, process, materials, software, and process control to deliver results on the wafer. Its products help customers build smaller, better performing devices used in mobile phones, personal computers, cloud and enterprise servers, wearables, automotive vehicles, and data storage devices.
Lam's products are organized around three process markets. Deposition includes the SABRE electrochemical deposition family for copper and other metals, the ALTUS family for tungsten and molybdenum CVD/ALD, the Striker ALD family, and the VECTOR PECVD family. Etch includes conductor etch (Kiyo, Versys Metal, Akara), dielectric etch (Flex, Vantex), deep silicon and through-silicon via etch (Syndion), and selective etch (Argos, Prevos, Selis). Clean includes Coronus plasma bevel cleaning and the wet clean families EOS, DV-Prime, Da Vinci, and SP Series. Lam also offers the Aether dry photoresist family for EUV patterning, plus solutions for wafer-level packaging, fan-out panel-level packaging, and 3D stacking of high bandwidth memory. Its products also serve related markets such as CMOS image sensors and MEMS. The Customer Support Business Group provides customer service, spares, upgrades, Equipment Intelligence fleet-level solutions, and new and refurbished non-leading edge products under the Reliant line.
Customers are leading semiconductor memory, foundry, and integrated device manufacturers that make NVM, DRAM, and logic devices. Its most significant customers in the last three fiscal years were Micron Technology, Samsung Electronics, SK hynix, and Taiwan Semiconductor Manufacturing Company. Demand is driven by artificial intelligence, cloud infrastructure, communications, automotive, and industrial applications. These applications push manufacturers toward 3D architectures, more sophisticated patterning, and new materials. A significant portion of sales and operations occurs outside the United States. Service engineers are located in the U.S., China, Europe, India, Japan, Korea, Southeast Asia, and Taiwan. Lam's business depends on the capital expenditures of semiconductor manufacturers.
Headquartered in Fremont, California, Lam maintains facilities across Asia, Europe, and the United States. Its manufacturing mainly consists of assembling and testing components, sub-assemblies, and modules, largely in cleanroom environments, before integrating them into finished systems shipped to or built at customer sites. It outsources certain manufacturing, production warehousing, and logistics functions to third parties. Some components and sub-assemblies come from single suppliers, and the company works to qualify alternative sources and sometimes carries excess inventory. Lam invests substantially in research and development and sells its systems with standard warranties covering defects in material and workmanship.
