KLA-Tencor Buying Vistec Unit

Jul 2008
MILPITAS, Calif., July 30, 2008 -- KLA-Tencor, a maker of equipment to detect defects in integrated circuits, today announced it will acquire the Microelectronic Inspection Equipment (MIE) business unit of Vistec Semiconductor Systems. Terms of the deal were not disclosed.

Vistec's MIE unit is located in Weilburg, Germany, and provides advanced semiconductor mask and wafer manufacturing systems. It is one of three international business units of Vistec Semiconductor Systems, which was formerly a part of Leica Microsystems and took on its current name in March 2006.

MIE makes mask metrology tools for registration metrology (pattern placement). It provides SEM (scanning electron microscopy) -based tools for mask critical-dimension measurement for 45-nm photomask production and 32-nm development. Other MIE technologies include macro defect inspection systems, overlay measurement systems for MEMS (microelectromechanical systems) applications and software for defect classification and data analysis.

“The Microelectronic Inspection Equipment division of Vistec not only complements KLA-Tencor’s product portfolio, it will give us an opportunity for growth into new segments of the mask and wafer markets,” said Rick Wallace, CEO of KLA-Tencor.

The transaction is subject to customary closing conditions, including regulatory approvals, and is expected to close before the end of 2008.

GLOSSARY
mask
1. A framelike structure that serves to restrict the viewing area of the screen whenplaced before a television picture tube. 2 In photolithography, a photomask (or mask) is typically a patterned transparent plate or an opaque plate with patterned holes or transparencies that uses a laser light source to transfer and print the pattern by an etching process onto a substrate that is typically a silicon wafer used in integrated circuitry. 
metrology
The science of measurement, particularly of lengths and angles.
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
wafer
A cross-sectional slice cut from an ingot of either single-crystal, fused, polycrystalline or amorphous material that has refined surfaces either lapped or polished. Wafers are used either as substrates for electronic device manufacturing or as optics. Typically, they are made of silicon, quartz, gallium arsenide or indium phosphide.
