Patent ID: 11899429
Assignee: SEMES CO., LTD.
Field: Control (Instruments)
Classification: CPC G  H | IPC G  H

Claim 11:
12. A substrate processing system comprising:
a transfer module configured to transfer a substrate;
a processing module configured to perform a fabrication process on the substrate; and
a controlling module,
wherein the controlling module comprises:
a first cluster tool controller (CTC) configured to control the transfer module and the processing module; and

a second CTC having the same configuration of a software and a hardware as configuration of a software and a hardware of the first CTC,
wherein, when the first CTC stops operating, the second CTC controls the transfer module and the processing module in place of the first CTC,
wherein the first CTC comprises:
a first processing unit configured to process data for controlling the transfer module and the processing module;
a first storage unit configured to store the data for controlling the transfer module and the processing module; and
a first interface unit configured to perform data exchanging with the second CTC, and

wherein the second CTC comprises:
a second processing unit configured to process the data for controlling the transfer module and the processing module while operating in synchronization with the first processing unit;
a second storage unit configured to store the data for controlling the transfer module and the processing module while operating in synchronization with the first storage unit; and
a second interface unit configured to perform data exchanging with the first CTC.
