Apparatus for producing polycrystalline silicon sheets and production method using the same

摘要

An apparatus (10) for producing a polycrystalline silicon sheet includes a crucible (1), a heating unit (5) for heating a starting material of silicon fed in the crucible (1), and a cooling unit (4) for contacting a melt of the starting material (S1) melted by heating to a cooling face (4a) of a cooling member, thereby obtaining a polycrystalline silicon sheet in which crystals of silicon are grown, wherein the cooling face (4a) of the cooling member has a sheet adhering portion for providing a silicon starting point of crystallization and allowing adhesion of the polycrystalline silicon sheet of grown crystals and a sheet stripping portion for allowing easy stripping of the polycrystalline silicon sheet.
