Notes:
We study for the effects of additional gas such as oxygen (O2) and hydrogen (H2) into SF6. When H2 gas was added to SF6, surface fluoride atomic concentration and surface roughness were lower than the other additional gases. Surface fluoride atomic concentration under this experimentwas reduced from 28 at % to 6 at % by the H2 addition. In post-processing, the fluoride atomic concentration was succeeded in a large reduction by processing H2, O2 plasma and high temperature hydrogen annealing. In hydrogen annealing, surface fluoride atomic concentration could be suppressed to less than 3 at %. This is new result succeeded in reduction of surface fluoride species greatly by hydrogen processing
