Zygo Corporation Ships First Front End Semiconductor Process Metrology Tool

Zygo Corporation (NASDAQ: ZIGO), a leading worldwide optical metrology supplier, today announced the first shipment of its new front end semiconductor metrology tool, the Z3D 7000(TM), to a leading tier one semiconductor manufacturer.

The Z3D 7000(TM) optical metrology tool performs high-resolution surface topography measurements on bare and patterned 200mm and 300mm semiconductor wafers. It provides high measurement precision at throughputs far exceeding those achievable with existing mechanical profiling techniques, such as atomic force microscopy. The tool has been designed to meet the growing need for in-line etch, deposition, and planarization process metrology 45nm node and beyond. It is equipped with SEMI® compliant automation, ISO Class 2 certified clean hardware, and meets all ergonomic and safety certifications needed for production line equipment.

Robert Stoner, ZYGO's Vice President, Metrology, made the following comment, "This is a significant shipment for ZYGO. We have listened carefully to some of the most influential voices in the semiconductor industry, and responded rapidly to their emerging process control needs with a powerful combination of proprietary ZYGO technologies, and a world-class platform. Our Semiconductor Group, which we formed less than a year ago, has quickly established itself, and we are optimistic about its future new semiconductor metrology products. The Z3D 7000(TM) is now a reality in the marketplace."

Zygo Corporation is a worldwide supplier of optical metrology instruments, precision optics, and electro-optical design and manufacturing services, serving customers in the semiconductor capital equipment and industrial markets.
