DEADLOCK DETERMINATION METHOD AND SEMICONDUCTOR APPARATUS
A deadlock determination method includes constructing a new WRG and determining a deadlock. At least a process step that includes a plurality of resources is selected from process steps in a WRG that supports transporting a single piece of material. The plurality of resources corresponding to the selected process step are combined. A total capacity of each of the process steps is changed according to a combination result to construct the new WRG that supports transporting a plurality of pieces of material. The plurality of resources include apparatuses for performing the process steps. The total capacity is a sum of a number of workstations of resources corresponding to each process step. Determining a deadlock includes determining whether a piece of material scheduling deadlock occurs based on the new WRG. The plurality of resources include apparatuses for performing the process steps.
Method of processing target substrate
A method of processing a target substrate includes a process of serially executing multiple processes including a main process and first to M-th subprocesses (where M is a positive integer). An index value indicating one execution of the main process is accumulated for each execution of the main process. The main process is executed multiple times in the process of serially executing multiple processes. An i-th subprocess (where i is a positive integer that satisfies 1≤i≤M) is executed once or multiple times in the process of serially executing multiple processes, and is executed subsequent to one or multiple consecutive executions of the main process. The i-th application and execution conditions are changeable.
TEACHING METHOD
A teaching method for a transfer mechanism is provided. The teaching method includes (a) placing a first substrate or an edge ring on a fork of the transfer mechanism, transferring the first substrate or the edge ring to a target position, and placing the first substrate or the edge ring onto the target position; (b) placing a second substrate having a position detection sensor on the fork, and transferring the second substrate to a position directly above or below the target position; (c) detecting an amount of deviation between the first substrate or the edge ring and the target position using the position detection sensor of the second substrate; and (d) correcting transfer position data of the transfer mechanism for the first substrate or the edge ring to be transferred next, based on the detected amount of deviation.
SEMICONDUCTOR MANUFACTURING APPARATUS AND METHOD FOR TRANSFERRING WAFER
A semiconductor manufacturing apparatus includes one or more process modules, a scheduler, and a transfer controller. A product wafer of a lot that is transferred from a load port to one of the one or more process modules is replenished such that a total number of wafers that are simultaneously processed in the one or more process modules becomes N. When an advance lot being processed and a post lot to be processed subsequent to the advance lot have a same processing condition, the scheduler creates the transfer plan to replenish with the product wafer of the post lot instead of a dummy wafer such that the transfer controller transfers the product wafer and the dummy wafer to the one or more process modules according to the created transfer plan.
