Abstract

A manufacturing method for a polysilicon thin film is provided. The manufacturing method for a polysilicon thin film includes forming a polysilicon layer, treating a surface of the polysilicon layer so that the surface of the polysilicon layer is electronegative, and supplying polar gas into a process chamber so that polar molecules of the polar gas are adsorbed on the surface of the polysilicon layer which is electronegative so as to form the polysilicon thin film, a surface of which has a hole density higher than an electron density.
