KLA-Tencor Corporation is a global, capital equipment company based in Milpitas, California. It supplies process control and yield management products for the semiconductor, data storage, LED, and related nanoelectronics industries. The company's products, software and services are intended for all phases of integrated circuit chip production, from research and development to wafer fabrication and advanced packaging processes, to final volume development.
KLA-Tencor’s products and services are used by the vast majority of bare wafer, IC, lithography reticle and disk manufacturers around the world. These customers rely on KLA-Tencor’s inline wafer and IC defect monitoring, review and classification; reticle defect inspection and metrology; packaging and interconnect inspection; critical dimension (CD) metrology; pattern overlay metrology; film thickness, surface topography and composition measurements; measurement of in-chamber process conditions, wafer shape and stress metrology; computational lithography tools and overall yield and fab-wide data management and analysis systems.
K-T Services is the company’s global service network that maintains the productivity and performance of all of its tools. It formally established its foundation in 2000, KLA-Tencor Foundation, which supports various global giving efforts.
On 21st Oct 2015, Lam Research reached a settlement with KLA-Tencor to acquire KLA-Tencor for $67.02 a share. The deal is expected to complete by Summer of 2016.
KLA-Tencor was formed in 1997 through the merger of KLA Instruments and Tencor Instruments, two companies in the semiconductor equipment and yield management systems industry.
