Abstract:
1. A method of fabricating a semiconductor device comprising: a step A of forming a polycrystalline or amorphous preliminary semiconductor layer on a surface of a substrate so as to have an opening portion; and a step B of simultaneously forming an epitaxial growth layer on an exposed portion of a surface of the substrate through the opening portion and a non-epitaxial growth layer on the preliminary semiconductor layer using a CVD growth method while heating the substrate inside a reaction chamber by means of a heat source inside the reaction chamber, the epitaxial growth layer being made of single crystalline semiconductor, and the non-epitaxial growth layer being comprised of a polycrystalline or amorphous semiconductor layer, wherein the preliminary semiconductor layer has a layer thickness of not less than 50 nm and not more than 150 nm.
