KLA-Tencor was formed in April 1997 through the merger of KLA Instruments (KLA) and Tencor Instruments (Tencor), two long-time leaders in the semiconductor equipment industry. Prior to the merger, both businesses served a segment of the inspection and metrology area; with KLA focused on defect inspection and Tencor placing its emphasis on metrology. Merging together in a one-to-one stock swap valued at $1.3 billion, KLA-Tencor became the most important process control player in the industry, bringing to market a complete line of yield management products and services from a single company.

KLA was named after its founders, Ken Levy and Bob Anderson. The word “Tencor” came about because the founder of Tencor, Karel Urbanek, wanted a two syllable name that would be easy to remember.

KLA Instruments was first established in 1975, with its first product emerging on the market in 1978—an automated inspection system that reduced photomask inspection time from eight hours to 15 minutes. Shortly thereafter, KLA Instruments went public and expanded its inspection product portfolio to include patterned wafer inspection systems. Two years later, KLA further broadened its offerings into the wafer metrology business through optical overlay and line-width measurement systems. During the subsequent few years, the company expanded its product base through the development of software tools to help integrate inspection and measurement data for analysis—ultimately forming the industry’s first yield management group to provide customers with expertise in yield enhancement through engineering consulting services.

1977, Tencor Instruments established its name, and first introduced its product—the Alpha-Step stylus surface profiler—just seven months later. This tool provided significant improvement in step-height measurement, a critical parameter in measuring film layer thickness. In 1984, Tencor Instruments launched its first Surfscan product—a particle and contamination defect system based on laser scanning technology, which soon became the production standard. By the late 1990s, Tencor had broadened its product offerings to also include defect review and data analysis tools. Following an initial public offering in 1993, Tencor then acquired Prometrix, a leading supplier of thin-film measurement tools, and further expanded its product offering. At the time of its merger with KLA, Tencor had revenues of approximately $403 million and 1,400 employees around the world.

Since the merger in 1997, KLA-Tencor has acquired the following companies:

· 1998 • Amray Inc. • Nanopro GmbH • The Quantox product line from Keithley Instruments, Inc • VARS • The Ultrapointe subsidiary of Uniphase Corporation

· 1999 • ACME Systems Inc.

· 2000 • Fab Solutions, from ObjectSpace Inc. • FINLE Technologies, Inc.

· 2001 • Phase Metrics

· 2004 • Candela Instruments • Wafer Inspection Systems business of Inspex, Inc.

· 2006 • ADE Corporation

· 2007 • OnWafer Technologies • SensArray Corporation • Therma-Wave Corporation

· 2008 • ICOS Vision Systems Corporation NV • Microelectronic Inspection Equipment (MIE) business unit of Vistec Semiconductor Systems

· 2010 • Ambios Technology

KLA-Tencor continues to serve the semiconductor equipment industry and also a number of other industries, including the light emitting diode (LED), data storage and photovoltaic industries, as well as general materials research. With a comprehensive portfolio of products, services, software and expertise, KLA-Tencor helps nanoeletronics manufacturers manage yield throughout their fabrication process—from research and development to final volume production. Designed to accelerate development and production ramp cycles, KLA-Tencor’s products and solutions help customers achieve higher and more stable, while improving overall profitability.

Karel Urbanek

1938 – 1991
Founder of Tencor Instruments

Karel Urbanek founded Tencor Instruments, which merged with KLA Instruments in 1997 to form what is today the fourth largest semiconductor capital equipment supplier—KLA-Tencor.

After graduating from the Charles University Faculty of Mathematics and Physics in 1963, Urbanek immigrated to the United States from Prague, Czechslovakia. He spent a short time at MIT’s Lincoln Labs in Cambridge before moving to the San Francisco Bay Area, where, after five years at Varian Associates, he founded Randex, Inc.—a maker of sputtering equipment for semiconductor manufacturing. In 1976, Urbanek founded Tencor Instruments, which provided measurement and process control equipment for the manufacture of semiconductor chips.

In 1977, seven months after the company’s inception, Tencor Instruments introduced its first product, the Alpha-Step™. Seven years later, Tencor Instruments launched Surfscan™, a product that detects particles on wafers, which continues to be a part of KLA-Tencor’s leading defect detection product portfolio today. Urbanek continued his leadership of the thriving company as its CEO and Chairman of the Board until his untimely death in 1991.

In 1986, Urbanek became a member of the SEMI board of directors and later vice chairman and member of the executive committee of the board. Urbanek was a dedicated leader of the SEMI International Standards Program, which continues to be a cornerstone of the semiconductor industry. The Karel Urbanek Award, established in 1992, is the most prestigious honor for participants in the SEMI International Standards Program. It is presented regularly to outstanding program members who uphold and further Urbanek’s contributions to the development of standards for the semiconductor and related microelectronics industries.
