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. For more information, visit: www.kla-tencor.com
