Abstract:
1. A method of forming an amorphous silicon film on a base, the method comprising: adsorbing an aminosilane onto the base by heating the base and supplying an amino silane-based gas to the heated base; forming the amorphous silicon film on the base onto which the aminosilane is adsorbed by heating the base and supplying a silane-based gas containing no amino group on the heated base onto which the aminosilane is adsorbed; and etching the amorphous silicon film to decrease a film thickness of the amorphous silicon film, wherein the amino silane-based gas is selected from gases comprising at least one of diisopropyl aminosilane (DIPAS), tridimethyl aminosilane (TDMAS), and bisdiethyl aminosilane (BDEAS).
