摘要: Aspects of the disclosure provided herein generally relate to a fluid flow network configured to cool subsystems of a substrate processing system. Aspects of the disclosure provide a fluid flow network and method that adjusts the flow of the cooling fluid through each subsystem of the substrate processing system. The methods described herein can include maintaining a flow rate of the cooling fluid through each subsystem over a range of cooling fluid pressures. The methods described herein can further include configuring the fluid flow network to equalize a flow rate of the cooling fluid through similar subsystems such that the flow rate through each subsystem is similar without adjustment.

摘要: Embodiments disclosed herein include a substrate processing module and a method of moving a workpiece. The substrate processing module includes a shutter stack and two process stations. The shutter stack is disposed between the process stations. The method of moving a workpiece includes moving a supporting portion from a first location to a shutter stack in a first direction, retrieving the workpiece from the shutter stack, and moving the supporting portion to a second location. The transfer chamber assembly and method allows for moving workpieces to and from the shutter stack to the two process stations. A central transfer robot of the substrate processing module is configured to grip both substrates and shutter discs, allowing for one robot when typically two robots would be required.
