  • Patent number: 11908712
    Abstract: A semiconductor manufacturing apparatus including a plurality of process modules for performing desired processes on a plurality of substrates and a plurality of transfer modules for serially transferring the plurality of substrates to the plurality of process modules is provided. The semiconductor manufacturing apparatus comprises a scheduler for calculating a cycle time so that a difference in time required for each of the desired processes is within an allowable time range and generating a transfer plan for the plurality of substrates based on the cycle time, and a transfer controller for controlling the plurality of transfer modules so that the plurality of substrates are serially transferred to the process modules according to the generated transfer plan.

  • Publication number: 20220148898
    Abstract: A substrate processing system for performing processing on a plurality of substrates. The substrate processing system comprises: a processing unit comprising a plurality of processing modules each configured to perform a predetermined process; a transfer unit having a transfer device configured to transfer a substrate to each of the plurality of processing modules; a loading/unloading unit configured to hold a plurality of substrates and load/unload a substrate to/from the processing unit; and a controller configured to control the processing unit, the loading/unloading unit, and the transfer unit. The controller controls the transfer unit to transfer to the plurality of processing modules in a serial manner a plurality of substrates that are sequentially loaded from the loading/unloading unit to the processing unit, the controller further comprises a standby mode setting unit configured to set a standby period of the substrate at an appropriate timing depending on a content of the process.

  • Patent number: 11127615
    Abstract: A substrate processing system includes a processing section that includes a plurality of process modules each of which performs a predetermined processing; a carrying-in/out section that holds the plurality of substrates, and carries the substrates into/out of the processing section; a transfer unit that transfers the substrates; and a controller that controls the processing section, the carrying-in/out section, and the transfer unit. The controller performs a control such that the plurality of substrates is sequentially transferred from the carrying-in/out section to the processing section, and the transferred substrates are sequentially and serially transferred to the plurality of process modules, sets an interval until a next substrate is unloaded after a substrate is unloaded from a predetermined module of the carrying-in/out section, and performs a control such that the plurality of substrates is sequentially unloaded from the predetermined module with a setting value of the interval.
