What KLA does
KLA Corporation (NASDAQ: KLAC) is a leading provider of process-control and process-enabling solutions for the semiconductor manufacturing industry, founded in 1976 and headquartered in Milpitas, California. The company designs, manufactures, and services inspection, metrology, yield-management, and chemistry process-control systems used by chip manufacturers to detect defects, control process variability, and improve yield across wafer fabrication, reticle production, advanced packaging, and PCB/IC substrate manufacturing. Its product portfolio spans multiple hardware families (Voyager, Puma, Surfscan, CIRCL, Kronos, Archer, SpectraShape, Teron, SPTS) and a software stack (aiSIGHT, Klarity, 5D Analyzer, OVALiS, PROLITH, I-PAT) that uses AI/ML for deep-learning defect classification, inline reliability screening, and cross-system process optimization. KLA also operates the KLA Instruments division for specialized metrology (optical profilers, nanoindenters, thin-film reflectometers) and KLA Pro Systems for certified/remanufactured tools serving IoT, automotive, and mobile segments.
KLA's commercial model is direct enterprise sales to semiconductor manufacturers, with an installed base of more than 57,000 tools generating recurring service revenue that is targeted to approach 25% of total revenue by 2030. Approximately 90% of revenue is derived from semiconductor process control equipment sold to a small set of mega-customers — TSMC, Samsung Electronics, SK Hynix, Micron, and Intel — that together represent the bulk of global leading-edge logic and memory capex. KLA reported FY2025 revenue of $12.16 billion with 35% net margins and 33% ROIC, held 73.8% of the global metrology and inspection market in 2025, and is guiding to a long-term revenue target of approximately $26 billion by 2030, a 13-17% CAGR underpinned by AI-driven semiconductor complexity, advanced packaging growth, and the transition to panel-level packaging architectures such as CoPoS.
