KLA Corp
kla.comKLA Corp (NASDAQ: KLAC) is a semiconductor capital equipment company that designs, manufactures, and sells process control and yield management systems used across the semiconductor and electronics manufacturing supply chain. Revenue comes from equipment sales across three primary segments: Semiconductor Process Control, Semiconductor Specialized Technologies, and PCB, Display and Component Inspection, supplemented by service programs sold to chip, wafer, reticle, and packaging manufacturers. TSMC and Samsung Electronics each accounted for more than 10% of total revenues in fiscal years ended June 30, 2025 and 2024, indicating meaningful customer concentration at the top. A majority of revenues are derived from outside the U.S., with China, Taiwan, Korea, Japan, Europe, and Israel as primary geographic regions (FY2025, 10-K filed 2025-08-08). KLA performs system assembly and testing in-house at facilities in the U.S., Singapore, Israel, Germany, U.K., Italy, and China, while outsourcing component and subassembly manufacturing to third-party vendors.
Products & Services
Semiconductor Process Control products include wafer defect inspection and review systems (Surfscan Series, eDR7380, eDRX Series), metrology systems (WaferSight Series, MicroSense wafer geometry family), reticle inspection and metrology systems (Teron SL6xx, TeraScan 5xx, X5.x Series, FlashScan Series, LMS IPRO Series), and packaging inspection systems (Kronos Series, Micro-SR, CIRCL-AP, irArcher Series). Semiconductor Specialized Technologies includes chemistry process monitoring systems (PWG5, eDR7380, QualiSurf Series, QualiLab Elite Series) and the SensArray product family for in-situ process management. PCB and Component Inspection products include direct imaging, inspection, optical shaping, inkjet, and additive printing systems under the Orbotech brand (Serena, Orbotech Corus, Orbotech Infinitum, Orbotech Diamond, Orbotech Ultra Fusion, Orbotech PerFix Series) and component inspection systems (ICOS F26x, ICOS Tx Series, Zeta-5xx/6xx). Semiconductor Software Solutions include the Klarity product family for run-time process control, defect excursion identification, and process corrections, as well as patterning simulation software for EUV lithography and multiple patterning techniques.
Revenue Model
KLA generates revenue through capital equipment sales to semiconductor, wafer, reticle, packaging, and PCB manufacturers, along with recurring service programs that help customers maintain system performance and productivity. Revenue is transactional for equipment and contract-based for service arrangements.
Customers & Markets
KLA's largest customers as of FY2025 and FY2024 (fiscal years ended June 30) include TSMC and Samsung Electronics, each exceeding 10% of total revenues. The customer base spans leading semiconductor manufacturers, wafer and reticle makers, advanced packaging manufacturers, and PCB and IC substrate producers in Asia, the U.S., and Europe. Key end markets include leading-edge foundry and logic (including 2-nanometer node production), DRAM memory, AI and high-performance computing advanced packaging, 5G, automotive electronics, and legacy node chip manufacturing. China is a significant end market for legacy node logic and memory chips and for PCB manufacturing (10-K, filed 2025-08-08).
Geographic Exposure
A majority of revenues are derived from outside the U.S., with China, Taiwan, Korea, Japan, Europe, and Israel as named geographic regions (FY2025, 10-K filed 2025-08-08). Manufacturing occurs in the U.S., Singapore, Israel, Germany, U.K., Italy, and China. China faces export control restrictions, with U.S. Commerce Department licensing requirements applying to certain China-based customers and entities on the U.S. Entity List.
