SEMI E94: Specification for Control Job Management
This standard was developed to provide a supervisory level of control for Process Jobs, giving hosts the ability to manage complex or repetitive processing scenarios. Control Jobs can contain multiple Process Jobs, which can be run in a specific order or be optimized for material throughput. As Control Jobs are defined, they are added to a queue; when a job reaches the top of the queue, it can begin executing if its material has arrived at the equipment and is available for processing. The factory host can either change the queue order to move priority jobs to the head of the queue, or explicitly Start, Stop, Abort, Pause, or Resume the head-of-queue job. Once processing is complete, Control Jobs can specify alternate material routing based on a predetermined plan or in response to processing results.
A number of our products support SEMI E94.
