KLA (KLAC)

KLA is best known for inspection and metrology systems used by leading foundries, memory producers, and integrated device manufacturers. As semiconductor features become smaller and chip designs more complex, manufacturers need increasingly sophisticated equipment to identify microscopic defects and variations that can affect performance or reduce yield. KLA’s systems support this need by combining optics, sensors, data analytics, and process knowledge to give fabs detailed information about what is happening on the wafer.

The company’s customer base includes many of the world’s largest chipmakers, including major foundries and memory manufacturers such as TSMC and Samsung. Its exposure is closely linked to semiconductor capital spending, technology transitions, and the construction or upgrading of fabrication plants. While process control is its core strength, KLA also has more limited participation in other parts of wafer fabrication equipment, including selected etch and deposition activities.

For investors, KLA stands out because process control is essential in both leading-edge and mature-node semiconductor production. The company benefits from the growing complexity of chip manufacturing, where improving yield can be as important as adding capacity. Its business is cyclical, but its technology is deeply embedded in the economics of modern semiconductor manufacturing.
