Patent ID: 8252669

Claim:
A method for manufacturing a microcrystalline semiconductor film, comprising the steps of: forming a plasma region between a first electrode and a second electrode by supplying high-frequency power of 60 MHz or less to the first electrode under a condition where a pressure of a reactive gas in a reaction chamber of a plasma CVD apparatus is set to greater than or equal to 450 Pa and less than or equal to 13332 Pa, and a distance between the first electrode and the second electrode of the plasma CVD apparatus is set to greater than or equal to 1 mm and less than or equal to 20 mm; forming crystalline deposition precursors in a gas phase including the plasma region; forming a crystal nucleus of greater than or equal to 5 nm and less than or equal to 15 nm by depositing the crystalline deposition precursors over a substrate; and forming a microcrystalline semiconductor film by growing a crystal from the crystal nucleus.
