KLA Corporation Supply Chain
Foundries and memory manufacturers need to measure what their production processes are doing, as well as perform those processes. KLA's displayed customers span those two manufacturing settings: TSMC makes chips for other designers, while Samsung Electronics and Micron bring memory production into the set.
Foundry and memory buyers in the displayed set
- Taiwan Semiconductor Manufacturing Company LimitedTaiwan | KLA Corporation supplies this customer | #1 of 3 by available USD-normalized size
- Samsung Electronics Co., Ltd.South Korea | KLA Corporation supplies this customer | #2 of 3 by available USD-normalized size
- Micron Technology, Inc.the United States | KLA Corporation supplies this customer | #3 of 3 by available USD-normalized size
Taiwan Semiconductor Manufacturing Company Limited, Samsung Electronics Co., Ltd. and Micron Technology, Inc. all manufacture semiconductors, but their production mixes differ. TSMC represents the foundry business; Samsung and Micron add memory manufacturing. The common thread is factory process control, rather than a shared consumer market for the chips they produce.
Inspection and measurement inside chip production
KLA develops process-control and process-enabling equipment for wafers, reticles, integrated circuits, packaging and printed circuit boards. Inspection and measurement help manufacturers identify defects and assess process results. That places KLA at a different point in a fab's equipment mix from vendors whose tools primarily deposit or remove material.
Photonics, subsystems and instrumentation upstream
- Coherent Corp.the United States | Supplier to KLA Corporation | #1 of 3 by available USD-normalized size
- Ultra Clean Holdings, Inc.the United States | Supplier to KLA Corporation | #2 of 3 by available USD-normalized size
- MKS Inc.the United States | Supplier to KLA Corporation | #3 of 3 by available USD-normalized size
Coherent Corp. operates in photonics, Ultra Clean Holdings, Inc. makes semiconductor subsystems, and MKS Inc. offers instrumentation, vacuum and photonics technologies. Those business capabilities give context to the three upstream edges. The snapshot does not identify the component or system purchased from each supplier, so it cannot assign a particular laser, valve or instrument to a KLA product.
Reading the breadth of KLA's customer network
The broader record contains 133 customers and 51 suppliers. That greater downstream coverage makes the customer network a useful starting point for discovering where KLA equipment is used. These counts describe the mapped network; they do not establish which customer contributes the most revenue.
