Patent ID: 8557720

Claim:
A substrate processing apparatus comprising: a processing chamber configured to process a substrate having a front surface including a dielectric; a substrate support member provided within the processing chamber to support the substrate; a microwave supplying unit configured to supply a microwave to a front surface side of the substrate supported on the substrate support member; a conductive substrate cooling unit which is provided below a rear surface side of the substrate supported on the substrate support member and has an opposing surface facing the rear surface of the substrate; and a control unit configured to control the substrate support member such that a distance between a top of the substrate support member and the opposing surface of the substrate cooling unit corresponds to an odd multiple of ¼ wavelength of the microwave supplied when the substrate is processed, wherein the control unit is further configured to control, after processing the substrate, the substrate support member such that the distance between the top of the substrate support member and the opposing surface of the substrate cooling unit is shorter than the distance during processing the substrate.
