Chipmakers use KLA’s tools to detect tiny defects, measure manufacturing results and identify process problems so more chips meet specifications. This work, known as process control and yield management, accounts for the great majority of KLA’s sales. Customers buy its inspection and measurement systems and software for use from research and development through high-volume production, mostly through KLA’s direct sales force.
Equipment sales provide most revenue. KLA also earns recurring revenue from maintenance and support contracts that help keep customers’ tools running and extend their useful lives. Service demand depends on the equipment installed at customer sites, how much customers use it and whether they renew their contracts.
The business depends on chipmakers’ equipment investment, which follows demand for chips and the capacity customers need. Sales are concentrated among a limited number of manufacturers, with Taiwan Semiconductor Manufacturing Company (TSMC) a substantial customer. Asia is a major market, and China supplies a significant share of revenue. Export controls restrict KLA’s ability to sell, ship or support certain products for some customers, particularly semiconductor manufacturers in China, unless it obtains the required licenses.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
KLA hinges on chipmakers’ equipment spending and how much process control they need, with Hitachi High-Tech and Lasertec also worth watching as competitors absent from this list.
Applied Materials competes for the chipmakers’ spending that funds KLA’s defect-detection and measurement equipment, selling inspection, metrology and process-control tools of its own. Its integrated tools for inspecting complex chip structures are worth watching for pressure on KLA’s orders and pricing.
Onto Innovation competes with KLA for wafer, chip and advanced-packaging manufacturers’ spending on tools that find defects and measure structures. Watch its optical measurement and advanced-packaging process-control products, where the two companies overlap.
Lam Research and KLA depend on the same memory and foundry equipment-investment cycle: Lam sells tools that process wafers, while KLA sells tools that check the results. Lam’s business with memory and foundry manufacturers offers a view of the customer spending behind KLA’s demand.
ASML both competes with KLA in process control and supports its demand by selling chipmakers equipment that prints patterns on silicon using extreme ultraviolet light, or EUV. Watch EUV adoption in advanced logic and DRAM: wider use increases demand for KLA’s inspection and measurement tools.
Nova competes with KLA for chipmakers’ spending on measuring dimensions, thin films and chemicals to keep manufacturing processes under control. Its systems that analyze and replenish chemicals during electroplating show the chemical-control side of that overlap.
TSMC is a major paying customer for KLA’s process-control equipment, contributing more than 10% of KLA’s total revenue in each fiscal year ended June 30, 2024, 2025 and 2026. It manufactures chips from customers’ designs; its investment in manufacturing capacity, especially advanced processes such as 2-nanometer, matters directly to KLA’s equipment demand.
Camtek competes with KLA for semiconductor manufacturers’ purchases of systems that inspect and measure wafers and packaging production. Its equipment covering later wafer-processing stages through the start of assembly, including diced-wafer inspection, marks the area to watch.
MKS and KLA share exposure to semiconductor-equipment investment and more complex manufacturing: MKS sells subsystems and light-based technologies used in equipment, while KLA sells complete defect-detection and measurement systems. MKS’s photonics offerings for inspection and metrology are the relevant business to watch, not evidence of a disclosed supply relationship with KLA.
Entegris and KLA serve chipmakers’ need for higher yields as production becomes more complex: Entegris sells high-purity materials and products that prevent contamination, while KLA sells tools that detect defects and monitor yields. Entegris’s filtration and purification business is a useful window into those tighter purity requirements.
Lam Research Corp earningsLRCX
Lam Research's report will show whether memory and foundry equipment spending is supporting the same chipmakers whose investment drives demand for KLA's process-control tools.
Read Lam Research's sales alongside what it says about memory and foundry customers' spending. Strength in both would suggest chipmakers are funding wafer-processing tools as well as the inspection and process-control tools used alongside them. Weakness in both would mean less support for KLA from this investment cycle, but would not establish how KLA's own orders are doing.
KLA Corporation earningsThis company
KLA's report will show whether chipmakers are buying more of its wafer-inspection and patterning systems alongside the service income from tools already installed.
Read product revenue alongside service revenue, and watch gross margin. If both revenue streams grow and gross margin holds, chipmakers are adding process-control tools while the installed base keeps generating service income. If product revenue stalls or falls while services grow, existing tools are supporting revenue, but demand for new equipment is lagging.
Onto Innovation Inc. earningsONTO
Onto Innovation's report will show whether chipmakers are spending more or less on wafer, chip and advanced-packaging inspection and measurement tools, areas where it competes with KLA.
Watch sales of Onto Innovation's optical-measurement and advanced-packaging process-control products. Growth would show customers are spending on tools that overlap with KLA's, but would not prove Onto took orders from KLA. Weakness would point to a softer market for those tools, not by itself to KLA losing customers.
