Patent ID: 8021979

Claim:
A manufacturing method of a semiconductor device, comprising: (a) placing a semiconductor wafer, having a first surface and a second surface opposite to the first surface, on a wafer stage provided in a first chamber in a treatment system; (b) performing dry cleaning treatment to the first surface of the semiconductor wafer by supplying reducing gas, which is excited by a plasma, through a showerhead set above the wafer stage; (c) after (b) performing the dry cleaning treatment, lifting the semiconductor wafer from the wafer stage in order to position the first surface of the semiconductor wafer closer to the showerhead than when the semiconductor wafer is on the wafer stage; (d) performing a first heat treatment to the semiconductor wafer at a first temperature utilizing a heating temperature of the showerhead; (e) transferring the semiconductor wafer from the first chamber to a second chamber in the treatment system; and (f) performing a second heat treatment to the semiconductor wafer at a second temperature higher than the first temperature in the second chamber.
