ConX300
Asyst ConX300 is a connectivity software solution for semiconductor equipment manufacturers. Asyst ConX300 supports 300mm fabs and 200mm fab upgrades. Asyst ConX300 supports SEMI 300mm connectivity standards for SECS/GEM, process management, carrier management, substrate tracking, and control jobs.[1][2][3]
What it is
General reference — not yet source-verifiedConnectivity software of this class provides the communication interface between a piece of semiconductor process or metrology equipment and the factory host computer systems that supervise the fab. The software implements the standards-based messaging, state models, and data definitions that let equipment report its status and accept commands within an automated wafer fabrication facility.
How it works
The ConX300 is implemented as an embedded package software product that can be incorporated into 300mm wafer-compatible equipment to build an interface compliant with SECS, HSMS, GEM, and GEM300 without additional hardware. State models, object management, and scenarios compliant with the individual standards are implemented by calling functions according to the behavior of the equipment. Configuration management is text-based and does not require a dedicated screen. The software runs on Windows and Linux operating systems.[5][4]
Where it fits in the process flow
The ConX300 sits between individual semiconductor tools and the fab's host automation applications, providing the equipment-side communication link used in automated wafer fabrication. In a 300mm fab, the software supports carrier management, substrate tracking, and control jobs that coordinate how lots and carriers move through process equipment. The software also supports equipment productivity tracking, which gives fab host computers improved information about equipment productivity.[1][2]
