What it sells6

Wafer and mask inspection systems
Machines such as Surfscan and Teron inspect silicon wafers and chip-making masks to find and examine defects.
Wafer measurement systems
Machines such as Archer and SpectraShape measure features including pattern dimensions, film thickness and alignment between layers on a wafer.
Process-control software and sensors
Klarity software analyzes manufacturing data to help identify defects and adjust processes; SensArray sensors collect information about conditions inside chip-making equipment.

Chemical process-control equipment
Equipment such as QualiSurf checks chemicals used in manufacturing and monitors their condition and use.
Specialty wafer-processing equipment
SPTS and Primaxx equipment uses processes such as etching and deposition to make specialized semiconductor devices.
Circuit-board and packaged-chip inspection equipment
Orbotech equipment inspects and measures printed circuit boards and chip packages, and can help create circuit patterns on boards and substrates.

Who buys it4

Taiwan Semiconductor Manufacturing Company Limited is identified as a customer that accounted for more than 10% of KLA revenue in each of fiscal 2024, fiscal 2025 and fiscal 2026 (each fiscal year, high); KLA sells mainly through its direct sales force.
Semiconductor manufacturers, including foundry and logic chipmakers and memory-chip makers, buy inspection, measurement and related equipment and services.
Wafer, reticle or chip-making-mask, and chemical or materials manufacturers buy equipment to check quality during production.
Printed circuit board, chip-substrate and packaged-chip manufacturers buy inspection, measurement and circuit-patterning equipment.

What it stands on, and what could break it

What the business leans on

1KLA depends on chipmakers and other electronics manufacturers investing in factory equipment; those purchases vary with industry conditions, end-market demand and customer spending cycles.
2A majority of revenue comes from outside the United States; international revenue was approximately 87% (fiscal year ended 2026-06-30, high).
3Some parts and materials are available only from one supplier or a limited group of suppliers, which can affect production and delivery.
4KLA depends on being able to sell and support equipment in major semiconductor manufacturing regions, including China, where trade rules and export controls can limit sales.

What could go wrong

1Changes in semiconductor-industry investment, factory spending or demand for chips can lead customers to delay, change or cancel equipment orders.
2Export controls, tariffs and other trade restrictions can limit KLA's ability to sell or support products for customers, particularly in China.
3KLA identifies Taiwan Semiconductor Manufacturing Company Limited as a customer exceeding 10% of revenue in each of fiscal 2024, fiscal 2025 and fiscal 2026 (each fiscal year, high); disruption to that relationship could affect sales. Delays or shortages from sole-source and limited-source suppliers could also disrupt customer deliveries.
