Abstract: Execution control systems for optimizing the efficiency of manufacturing processes are described in this application. For example, an execution management system may optimize IC processes and scheduling by analyzing a number of desired metrics along with system constraints, such as tool availability, tool reliability, etc, along with information from conventional processing tools such as APC and SPC. The optimized processing schedule may then be implemented in real-time and updated with new process requests and current information relating to tools and other metrics, thereby reducing human interaction and inefficiency. Other embodiments are also described in this application.
