Asyst Wins Multiple Orders for Interface A and 300mm Software Products; Receives First Interface A Orders from Semiconductor Equipment Manufacturers.

FREMONT, Calif. -- Asyst Technologies, Inc. (Nasdaq:ASYT), today announced that its Asyst EIB(TM) and NexEDA(TM) software products have been selected by two large semiconductor equipment manufacturers for implementation on their tools. These are the first confirmed orders for software products compliant with Semiconductor Equipment and Materials International's (SEMI) new Interface A standards, which provide for real-time access to critical equipment data.

In addition, Asyst has been awarded an order from a major North American semiconductor equipment manufacturer for Asyst's 300mm automation software, ConX300(TM). This order is a three-year extension of a software agreement for ConX300 developer's kits, runtime licenses and testing tools. The extension is valued at approximately $1.6 million.

Julie Iskow, vice president of software engineering for Asyst, said, "These wins in the 300mm connectivity market validate our software solutions' use of standards, services, and innovation to deliver mission-critical results for equipment manufacturers and fabs. In the near future we expect to see more of these types of orders for ConX300 as well as for NexEDA, which combines the Interface A, 300mm, and SECS/GEM standards into a single product."

Asyst currently enjoys leading market share for 300mm connectivity solutions, and all of its connectivity products, including GWGEM, SDR, NexEDA and EIB, have a reputation for reliability, performance, and compliance with industry standards.

The ConX300 software agreement extension applies to a large number of the customer's product platforms. This renewal agreement follows a previous three-year period in which Asyst's software technology was found to both meet and exceed the customer's expectations. The company believes that Asyst ConX300 is in use in every 300mm fab in the world, with greater than 50 percent market share.

Rick Larson, director of business development for the Asyst Connectivity Solutions Group, observed, "I believe the decision to renew ConX300 was based on a good working relationship with the customer, as well as our having supplied a first class product. ConX300 provides a robust integration with the customer's tool software and has led to successful operations with fab automation systems worldwide."

Asyst's .Net-based Interface A solutions are unique in their ability to be used both on-tool and off-tool, and on new or existing manufacturing equipment. This allows end users and vendors to obtain an abundance of manufacturing data from the tools. This secure access is available to multiple clients, such as APC and SPC applications, from individual or multiple tools, and through multiple standard communication protocols. All Asyst Interface A solutions are fully compliant with the complete set of SEMI EDA requirements, including E121, E128, E120.1, E132.1, E125.1, and E134.1. Both EIB and NexEDA are in final Beta phase and scheduled to ship this month.
