Claim Text:
1. A method of forming a film including a silicon film on a base, comprising: forming a seed layer on a surface of the base by heating the base and supplying an aminosilane-based gas onto the heated base surface; and forming the silicon film on the seed layer by heating the base and supplying a silane-based gas containing no amino group onto the seed layer of the surface of the heated base, wherein a molecule of the aminosilane-based gas used in forming a seed layer comprises two or more silicon atoms, and wherein the aminosilane-based gas containing two or more silicon atoms in the aminosilane-based gas molecule is selected from gases containing at least one of amino silicon compounds represented by the following formula: wherein in Formula (B), n is the number of amino groups, which is a natural number of 1 to 6, m is the number of alkyl groups, which is 0 or a natural number of 1 to 5, R1=CH R1=R2=R3, or they may not be the same, R3=Cl, and X is a natural number of not less than 2.
