KLA is a provider of process control and yield management solutions for the semiconductor and related microelectronics industries. The company designs and manufactures equipment, software and services used by chipmakers to analyze and control manufacturing processes, detect defects, measure critical dimensions and improve yield across wafer fabrication, photomask and packaging operations. KLA’s offerings are aimed at enabling production of advanced logic, memory, and specialty devices at progressively smaller technology nodes and more complex package structures.
Its product portfolio includes optical and e-beam inspection systems, metrology tools for critical dimension and film measurement, mask and reticle inspection platforms, as well as enterprise software and data analytics that aggregate process data and drive automated process control. In addition to hardware, KLA provides installation, calibration, training and field support to help customers integrate its systems into high-volume manufacturing environments and maintain process performance over time.
The company traces its modern form to the combination of two legacy process-control businesses in the semiconductor industry; the merged organization has since evolved to support a wide range of customers and technology nodes. KLA operates globally, serving semiconductor manufacturers, foundries, integrated device manufacturers, and suppliers to the electronics industry with sales, service and R&D footprints across North America, Asia and Europe.
KLA emphasizes ongoing research and development to address challenges from device scaling, new materials and advanced packaging, and it plays a central role in customers’ efforts to improve yield and throughput. Its products and services are considered critical components of the semiconductor manufacturing toolset, helping fabs reduce variability, identify defects early and optimize production efficiency.
