GWconX300 was originally designed to handle the manufacturing-communications requirements of fixed-buffer equipment, in which a load port bolted onto the outside of the tool interfaces with an automated material-handling system (AMHS) to load FOUPs back and forth for processing. While about 90 percent of semiconductor-manufacturing tools utilize this kind of structure, a small but critical percentage of equipment, including such tools as diffusion furnaces and wet benches, contains internal buffers. These systems, which intake, process and store FOUPs via a FOUP buffer or mini-stocker, essentially include part of the AMHS within the equipment and, therefore, require much more complicated software to address internal connectivity challenges.

"Our goal in adding these enhancements to GWconX300 was twofold," said Paula LuPriore, vice president/general manager, Connectivity Solutions at Asyst Technologies. "First, it is our goal to make GWconX300 the de facto industry standard for advanced 300mm tool connectivity, and it is therefore, important that the product be capable of running on all tools in a fab. Second, since internal-buffer-based systems do not use our load ports, this new capability provides an entrée into these markets and an opportunity to expand our 300mm technology reach."

GWconX300 is software for implementing communications links on semiconductor wafer fabrication equipment, using the new Semiconductor Equipment and Materials International (SEMI) standard protocols required for all 300mm and advanced 200mm factory-automation systems. It provides run-time software libraries designed for incorporation with the embedded control software of any type of 300mm equipment. GWconX300 also provides tools for rapid development and integration of connectivity software. Key features include automated handling of intercompatibility between new SEMI standards; field-configurable adjustments that ensure compatibility of equipment with older legacy host computers; automatic process, syntax checks and replies to all messages mandated by the specified SEMI standard; and hooks for synchronization with the SEMI E84 standard, which ensures a smooth handshake between production equipment and the AMHS. Currently in beta testing, the enhanced version of GWconX300 will be in production volume by the first quarter of next year. More information about Asyst's 300mm connectivity solutions will be presented at a workshop on December 5, at the Makuhari Prince Hotel, from 1:00-6:00 p.m. to coincide with SEMICON Japan 2002. Asyst also will be demonstrating its 300mm hardware and software solutions in its booth #7-B301 at SEMICON Japan, December 4-6, at the Makuhari Messe Exhibition Center, Chiba, Japan.
