KLA Corporation

KLA Corporation and its majority-owned subsidiaries are suppliers of industry-leading equipment and services that enable innovation throughout the electronics industry. We provide advanced process control and process-enabling solutions for manufacturing wafers, reticles/masks, chemicals/materials, integrated circuits ('ICs' or 'chips'), packaged ICs and printed circuit boards ('PCBs'), as well as comprehensive support and services across our installed base. Our suite of advanced products, coupled with our unique process control software and services, allows us to deliver solutions that help our customers achieve their technology advancement and high-volume production goals by improving yields while reducing waste, risks and costs. This improves our customers' overall profitability and return on investment. Our services business, which accounted for approximately 23% of our total revenues in fiscal 2026, provides maintenance and other services to maximize uptime, productivity and tool life for our customers. KLA was formed as KLA-Tencor Corporation in April 1997 through the merger of KLA Instruments Corporation and Tencor Instruments, two long-time leaders in the semiconductor capital equipment industry that began operations in 1975 and 1976, respectively. We are organized into three reportable segments: Semiconductor Process Control, Specialty Semiconductor Process and PCB and Component Inspection. Within the Semiconductor Process Control segment, our comprehensive portfolio of inspection, metrology and software products, as well as related services, help IC, wafer, reticle/mask and chemical/materials manufacturers achieve target yields throughout the entire fabrication process, from R&D to final volume production. Within the Specialty Semiconductor Process segment, we develop and sell advanced vacuum deposition and etching process tools, which are used by a broad range of specialty semiconductor customers, including manufacturers of microelectromechanical systems ('MEMS'), radio frequency ('RF') communication semiconductors, and power semiconductors for automotive and industrial applications. Within the PCB and Component Inspection segment, we enable electronic device manufacturers to inspect, test and measure PCBs, IC substrates and packaged ICs to verify their quality, pattern the desired electronic circuitry on the relevant substrate and perform three-dimensional shaping of metalized circuits on multiple surfaces.
