KLA Corporation is a capital equipment company based in Milpitas, California. It supplies process control and yield management systems for the semiconductor industry and other related nanoelectronics industries. The company's products and services are intended for all phases of wafer, reticle, integrated circuit (IC) and packaging production, from research and development to final volume manufacturing.[2]

History[edit]

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.[3] The merger was intended to create a single source for chip process and diagnostics equipment.[3] KLA Instruments was founded in 1975 by Ken Levy and Bob Anderson, and focused on photomask detection to identify chip defects. KLA later broadened its product line to include wafer inspection, wafer metrology and integrated inspection and analysis software.[4] Tencor was founded in 1976 by Czech scientist and US immigrant Karel Urbanek, along with colleague John Schwabacher.[5][6] The company initially focused on making precise measurements of semiconductor film layer thickness, and in 1984, developed laser-scanning technology to detect particle and other contamination. The company also developed defect review and data analysis equipment.[4] At the time of the merger, the companies' combined revenue was greater than $1 billion.[3]

In February 1998, KLA-Tencor acquired Freiburg, Germany-based Nanopro GmbH, a company that used advanced interferometric technology for wafer shape and thickness measurements.[7] In April, the company acquired Amray, Inc., a Bedford, Massachusetts-based provider of scanning electron microscope (SEM) systems for applications including semiconductor manufacturing.[8] In June, the company acquired San Jose, CA-based VARS, a developer of image archiving and retrieval systems.[7] In November, KLA-Tencor acquired the Quantox line of oxide monitoring products from Solon, Ohio-based measurement and instrument company Keithley Instruments.[9] In December, the company acquired the Ultrapointe subsidiary of Uniphase Corporation.[10]

In December 1999, the company acquired Taiwan-based yield analysis software maker ACME Systems.[11]

In February 2000, KLA-Tencor acquired Austin, Texas-based Finle Technologies, Inc., a developer of lithography modeling and analysis software.[12] In March, the company acquired Austin, Texas-based advanced process control (APC) software developer Fab Solutions, from parent ObjectSpace.[13]

In 2001, the company acquired yield management and process control company Phase Metrics, Inc.[14]

In 2004, KLA-Tencor acquired surface inspection system manufacturer Candela Instruments, Inc.[15] and the Wafer Inspection Systems business of Inspex, Inc.[16]

In 2006, the company acquired ADE Corporation, a supplier of silicon wafer metrology and related gear.[17]

In 2007, KLA-Tencor acquired lithography and plasma etch products manufacturer OnWafer Technologies,[18] temperature monitoring firm SensArray Corporation[18] and process control and metrology company Therma-Wave Corporation.[19]

In 2008, the company acquired test and measurement company ICOS Vision Systems Corporation NV,[20] and the Microelectronic Inspection Equipment (MIE) business unit of Vistec Semiconductor Systems, Inc.[21]

In 2010, KLA-Tencor acquired technology hardware company Ambios Technology, Inc.[21]

In 2014, the company acquired computational lithography and inspection company Luminescent Technologies, Inc.[21]

In 2017, the company acquired optical profiling and inspection company Zeta Technologies Co. Ltd.[21]

In 2018, KLA-Tencor acquired the Nano Indenter product line from Keysight Technologies. The company also acquired Nanomechanics Inc. and MicroVision.[21]

In March 2018, KLA-Tencor announced an agreement to acquire Yavne, Israel-based automated optical inspection equipment vendor Orbotech for approximately $3.4 billion.[22] Orbotech also owned Newport, Wales, UK-based SPTS Technologies Ltd, a manufacturer of etch, PVD and CVD wafer processing equipment for the MEMS, advanced packaging, LED, high-speed RF, and power management devices.[23]

On January 10, 2019, KLA-Tencor announced that they were changing their name to KLA Corporation.[24] In February, the company announced that its acquisition of Orbotech was complete.[22] The company's name change took effect in July 2019.[citation needed] In June, KLA announced plans to open a second US headquarters in Ann Arbor, Michigan. The facility was scheduled to open in summer 2021, with plans to host 500-600 new hires, around 50% of whom were to be engineers.[25] The facility would reportedly have a relationship with the University of Michigan and support automotive industry partnerships.

In July 2021, the company introduced new inspection products for automotive chips.[26] In November, KLA's new North American headquarters opened in Ann Arbor, Michigan.[27] The facility is 230,000 square feet, and is designed to support 1,000 employees.[27]

Products[edit]

KLA develops a range of advanced inspection tools, metrology systems, and computational analytics software used to improve manufacturing yields for a variety of standard and specialty semiconductors; printed circuit boards (PCBs); and flat panel displays.[1]

Its products are grouped into three segments:[1]

  • Semiconductor Process Control - a range of inspection, metrology and data analytics products, and related services, designed to increase manufacturing yields during the semiconductor fabrication process.
  • Specialty Semiconductor Process - advanced vacuum deposition and etching process tools, used to manufacture specialty semiconductors such as MEMS, radio frequency (RF) communication semiconductors, and power semiconductors for automotive and industrial applications.
  • PCB, Display and Component Inspection - inspection, testing and measurement equipment for manufacturers of PCBs, flat panel displays (FPD) and integrated circuits (ICs). The equipment is used to verify quality, produce consistent electronic circuitry patterns on relevant substrate, and perform three-dimensional shaping of metalized circuits on surfaces.

Operations[edit]

KLA's facilities include their global headquarters in Milpitas, California, as well as manufacturing, support and research and development facilities at multiple locations in the United States, India, Europe, Israel, Japan, and Asia/Pacific. The company also operates a second North American headquarters in Ann Arbor, Michigan.[27] The company reported 11,300 employees in 2021.[1]

Edward W. Barnholt is the company's Chairman, and Richard P. Wallace is CEO and President.[1]

KLA Foundation[edit]

KLA Foundation (originally KLA-Tencor Foundation) is the company's philanthropic arm, and was founded in 2000.[28] KLA Foundation supports and benefits the global communities in which KLA employees live, such as donations to the Milpitas school district, the American Red Cross, and Silicon Valley Leadership Group’s Covid-19 Aid Coalition.[29]
