<p>A substrate processing apparatus includes: a holding stage which includes a susceptor having a substrate holding surface on which a wafer is held and a focus ring holding surface on which a focus ring is held; an electrostatic chuck which electrostatically adsorbs a rear surface of the wafer to the substrate holding surface and electrostatically adsorbs a rear surface of the focus ring to the focus ring holding surface; and a heat transfer gas supplying mechanism, wherein the heat transfer gas supplying mechanism independently provides a first heat transfer gas supply unit supplying a first heat transfer gas to the rear surface of the substrate and a second heat transfer gas supply unit supplying a second heat transfer gas to the rear surface of the focus ring.</p> |
