Abstract

A method of manufacturing a polycrystalline silicon film includes: depositing a catalyst layer including nickel and depositing nickel nanoparticles on a substrate; exposing the catalyst layer and the nanoparticles to at least silane gas; and heat treating the substrate coated with the catalyst layer and the nanoparticles during at least part of the exposing to silane gas in growing a silicon based film on the substrate.
