Abstract:
A clean transferring and storing method for a semiconductor wafer, comprising:providing a clean box comprising a box body having an aperture in one surface, a lid configured to close said aperture hermetically, a gas inlet valve and a gas outlet valve provided in said box body, and a groove formed between said box body and said lid such that a suction space surrounding said aperture is formed when said clean box is closed by said lid;opening said gas inlet valve and said gas outlet valve when said aperture of said clean box is closed by said lid;introducing a non-oxidizing gas through said gas inlet valve to purge gases having been present in said clean box through said gas outlet valve so as to fill said box with the non-oxidizing gas; andclosing said gas inlet valve and said gas outlet valve so as to keep a semiconductor wafer stored in said clean box under non-oxidizing gas atmosphere.
