KLA Corporation supplies industry-leading equipment and services that enable innovation throughout the electronics industry. The company provides 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). KLA also offers comprehensive support and services across its installed base. Its services business accounted for approximately 22% of revenue in fiscal 2025. KLA was formed as KLA-Tencor Corporation in April 1997 through the merger of KLA Instruments Corporation (operations began 1975) and Tencor Instruments (operations began 1976). The company is organized into three reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection. The Semiconductor Process Control segment offers inspection, metrology, and software products, plus related services, to help IC, wafer, reticle/mask, and chemical/materials manufacturers achieve target yields from R&D to final volume production. The Specialty Semiconductor Process segment develops and sells advanced vacuum deposition and etching process tools used by specialty semiconductor customers, including manufacturers of microelectromechanical systems (MEMS), radio frequency (RF) communication semiconductors, and power semiconductors for automotive and industrial applications.
