Claim 18:
19. The method of claim 17:
wherein the first hydrogen flow rate and the first oxygen flow rate are such that the portions of the semiconductor wafer are exposed to a first combination of resultant hydrogen and oxygen;
wherein hydrogen is a first percent PT1 of the first combination and 15%≤PT≤33%;
wherein the second hydrogen flow rate and the second oxygen flow rate are such that the portions of the semiconductor wafer are exposed to a second combination of resultant hydrogen and oxygen;
wherein hydrogen is a second percent PT2 of the second combination and 15%≤PT2≤33%;
wherein the third hydrogen flow rate and the third oxygen flow rate are such that the portions of the semiconductor wafer are exposed to a third combination of resultant hydrogen and oxygen; and
wherein hydrogen is a third percent PT3 of the third combination and 15%≤PT3≤33%.
