Systems and methods for temperature control of semiconductor wafers
摘要:
Systems and methods for temperature control of semiconductor wafers are provided. An exemplary embodiment of semiconductor wafer is held by an electrostatic chuck. An exemplary embodiment of system includes a cooling apparatus connecting the electrostatic chuck. The cooling apparatus comprises an inlet, an outlet, a porous flow layer, a porous contact layer contacting the electrostatic chuck, and a porous heat exchange layer disposed between the flow layer and the contact layer. The inlet communicates with the flow layer, and the outlet communicates with the contact layer. The fluid medium is introduced into the flow layer from the inlet and sequentially flows through the heat exchange layer and the contact layer. The fluid medium is discharged from the contact layer through the outlet, thereby exchanging heat from the semiconductor wafer.
