Patent ID: 7103990

Claim:
A rotation silicon wafer cleaning device for performing drying and hydrogen termination treatment on an outer surface of a silicon wafer, comprising: (a) a case body; (b) a silicon wafer support and rotation driving mechanism disposed inside the case body; and (c) a silicon wafer drying device including (i) a gas supply panel having a gas mixer, the supply panel being disposed to supply a mix of hydrogen gas and inert gas, the mix comprising greater than 0.05% by volume of hydrogen; (ii) a mixed gas supply pipe coupled to the gas mixer; (iii) a mixed gas heating device disposed to heat the mixed gas in the mixed gas supply pipe; and (iv) a hydrogen radical formation and dispersion apparatus disposed to receive the heated mixed gas from the mixed gas supply pipe, having a platinum film disposed to form hydrogen radicals in the heated mixed gas, the hydrogen radical formation and dispersion apparatus disposed to direct the mixed gas containing hydrogen radicals onto a rotating silicon wafer.
