Tokyo, Japan, November 30, 1999 - In an announcement here at the opening of the SEMICON Japan 99, Asyst Technologies, Inc. (Nasdaq NM: ASYT) today unveiled the SMS substrate management system-the first in a new family of smaller, high productivity 200 mm wafer sorters used in semiconductor manufacturing. These management platforms are used primarily by semiconductor device manufacturers to manipulate and identify wafers during the manufacturing process.

Dennis Riccio, Asyst's senior vice president of Global Customer Operations, said, "The SMS is the first in a planned line of Asyst sorters that have been built to offer comprehensive, fully-automated manipulation capabilities with the throughput and yield improvements customers need for advanced device manufacturing lines."

The SMS has been designed for high throughput in a small footprint and is capable of handling 200 mm wafers in SMIF or open cassette environments. The system performs a range of operations including product identification, transfers, sorting, merging, orientation, verification and randomization, effectively becoming a single point of wafer manipulation and providing total manufacturing control.

Because the SMS is a fully-automated platform it ensures that wafers remain in a class 0.1 environment during all fab process steps. This "hands-off" approach helps manufacturers enhance yield by reducing handling-induced scratches and contamination. The SMS system also protects against misprocessing by performing a final verification of production lot integrity.

The SMS components include Asyst mini-environment and isolation technology, Asyst robotics for wafer handling, the Asyst VersaPortÔ SMIF front-end and Asyst graphical user interface software. The components are all modules designed and manufactured by Asyst, providing a compatible, cost-effective solution that can quickly and easily be configured to suit customer needs. Although the SMS system will replace Asyst's WMS wafer management platforms, the company will continue to support existing customer requirements.

Asyst has received multiple orders for the SMS. First delivery is anticipated in the first quarter of 2000. The new SMS system will debut at the Asyst exhibit at SEMICON Japan, December 1-3, 1999, at the Makuhari Convention Center, booth 6-A801.
