KLA Tencor
Encyclopedia
KLA-Tencor Corporation (NASDAQ
: KLAC) is a supplier of process control
and yield management
solutions for the semiconductor
and related microelectronics
industries. These technologies serve the semiconductor, data storage, LED, photovoltaic, and other related nanoelectronics industries. The company's portfolio of products, software, analysis, services and expertise is designed to help IC manufacturers manage yield throughout the entire wafer fabrication process-from R & D to final yield analysis.
KLA-Tencor offers a broad spectrum of products and services that include in-line wafer defect monitoring; reticle and photomask
defect inspection; wafer overlay; film and surface measurement; and overall yield- and fab-wide data analysis.
In the semiconductor industry, the fabrication of an integrated circuit (IC), or chip, is accomplished by depositing a series of film layers upon a silicon wafer, which forms the foundation of the chip. A single wafer may hold hundreds of chips, each of which will go on to power electronic devices such as MP3 players, cell phones, personal computers and more.
The chip is built layer by layer from patterned films of conducting, semiconducting or insulating materials. The role of KLA-Tencor’s products in this process is to monitor the defectivity and physical characteristics of each step, allowing the manufacturer to better control each process and maximize chip yield.
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. In 2011 KLA-Tencor celebrated its 35th anniversary.
fabrication process begins with a bare silicon wafer—a round disk that is six, eight or twelve inches in diameter, about as thick as a credit card and gray in color. The process of manufacturing wafers is itself highly sophisticated, involving the creation of large ingots of silicon
by pulling them out of a vat of molten silicon
. The ingots are then sliced into wafers and polished to a mirror finish.
The manufacturing cycle of an IC
is grouped into three phases: design, fabrication and testing. IC design involves the architectural layout of the circuit
, as well as design verification and reticle generation. The fabrication of a chip is accomplished by depositing a series of film layers that act as conductors, semiconductors or insulators. The deposition of these film layers is interspersed with numerous other process steps that create circuit
patterns, remove portions of the film layers, and perform other functions such as heat treatment, measurement and inspection. Most advanced chip designs require hundreds of individual steps, many of which are performed multiple times. Most chips consist of two main structures: the lower structure, typically consisting of transistors or capacitors which perform the “smart” functions of the chip; and the upper “interconnect” structure, typically consisting of circuitry which connects the components in the lower structure. When all of the layers on the wafer have been fabricated, each chip on the wafer is tested for functionality. The wafer is then cut into individual devices, and those chips that passed functional testing are packaged. Final testing is performed on all packaged chips.

Karel Urbanek (1938–1991)
Founder of Tencor Instruments
Karel Urbanek founded Tencor Instruments, which merged with KLA Instruments in 1997.
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.

The manufacturing processes KLA-Tencor’s tools affect include: chip manufacturing, wafer manufacturing, reticle manufacturing, data storage/media head manufacturing, photovoltaic (solar) manufacturing, high-brightness light emitting diode (HBLED) manufacturing, compound semiconductor manufacturing, MEMS manufacturing, and general purpose/labs.
KLA-Tencor’s core product selection includes inspection and metrology (measurement) tools for reticle, substrate and IC manufacturing.
Reticle Inspection - Error-free reticles and photomasks are the first step in achieving high yields, since reticle defects can be replicated on production wafers. Mask shops and IC fabs rely on KLA-Tencor’s high-sensitivity reticle inspection systems to ensure that masks are defect-free when they are shipped to the fab, and that they remain defect-free during the fabrication process.
Wafer Inspection - KLA-Tencor’s wafer inspection product line can be further divided into patterned wafer, monitor wafer and bare substrate inspection. Patterned wafer defect inspection, review and analysis tools allow engineers to detect, count, classify and characterize yield failures caused by particles, pattern defects and electrical issues during all stages of the chip manufacturing process. Monitor-wafer and bare-substrate defect inspection include specialized tools used to detect, count and bin defects, then assess surface quality on blanket (unpatterned) films and bare substrate surfaces for process and tool qualification and monitoring.
