How a process simulator has been integrated with a commercial computer-aided manufacturing (CAM) system to provide a set of powerful tools for process analysis, diagnosis, and control, is described. The CAM system acts as the interface to the simulator and maintains the simulation control data as part of the process specification. Making process simulation available in a manufacturing environment allows engineers to intuitively investigate the process thus aiding their understanding of the interrelation of process steps; it is believed that this is the first time such a system has been implemented. A misprocessing scenario in an ASIC facility is used to demonstrate how the system can be used to analyse options for corrective processing. Other applications exist in its use for documenting processes, to simplify process transfer and implementation, and investigating the effect of corrective processing on device reliability.
