Classification: CPC H | IPC H

Claim 0:
1. A method of forming an integrated circuit, the method comprising:
a first step including positioning a semiconductor wafer in a processing chamber;
a second step including exposing portions of the semiconductor wafer with:
introducing a first amount of hydrogen into the processing chamber; and
introducing a first amount of oxygen into the processing chamber, wherein a first temperature along an outer radius of the semiconductor wafer is less than a second temperature at a center radius of the semiconductor wafer; and

a third step including introducing a second amount of hydrogen and a second amount of oxygen into the processing chamber, wherein the second amount of hydrogen is greater than zero and less than the first amount of hydrogen or the second amount of oxygen is greater than zero and less than the first amount of oxygen.
