KLA designs, manufactures, and markets process control, process-enabling, and yield management solutions for the semiconductor and related electronics industries globally. Its operations are structured into three segments: Semiconductor Process Control.
Its portfolio also includes Specialty Semiconductor Process, and PCB and Component Inspection. It offers inspection and review tools to identify, locate, characterize, review, and analyze defects on various surfaces of patterned and unpatterned wafers.
Its portfolio also includes metrology systems to measure pattern dimensions, film thickness, film stress, layer-to-layer alignment, pattern placement, surface topography, and electro-optical properties for wafers, chemical process control equipment, wired and wireless sensor wafers and reticles, wafer defect inspection, review, and metrology systems, reticle inspection and metrology systems, wafer inspection and metrology systems, and semiconductor software solutions that provide run-time process control, defect excursion identification, process corrections, and defect classification to accelerate yield learning rates and reduce production risk, as well as etch, plasma dicing, deposition, and wafer processing technologies and solutions for the semiconductor and microelectronics industry.
Additionally, it offers direct imaging, inspection, optical shaping, inkjet and additive printing, and computer-aided manufacturing and engineering solutions for the PCB market and inspection and metrology systems for quality control and yield improvement in advanced and traditional semiconductor packaging markets. Incorporated in 1975 and headquartered in Milpitas, California, KLA was formerly known as KLA-Tencor Corporation before rebranding in July 2019.
