Abstract
A method is disclosed that includes the operations below: comparing an arrival time of a lot arrived at a process stage of N process stages with a processing time, determining whether one of tools at the process stage has a remain operation time which is equal to, or less than and closest to the arrival time, when a first tool of the tools has a first remain operation time which is equal to, or less than and closest to the arrival time, processing the lot with the first tool of the tools in the process stage after dispatching the lot to the processing stage, and generating at least one semiconductor device from the lot based on the comparing, determining and processing.
