Abstract:
A method of forming a film, comprising:carrying a process target into a film formation device; forming a poly-crystal silicon layer uniformly doped with first impurities of one conductive type on the process target by supplying a first film-forming gas into the film formation device, said first film-forming gas containing a silane-based gas and a first impurity gas which is a hydride of one of Group-III elements and Group-V elements; and forming a high-melting point metallic silicide layer uniformly doped with second impurities of one conductive type on the poly-crystal silicon layer by supplying a second film-forming gas into the film formation device, said second film-forming gas containing a gas including a high-melting point metal, a silane-based gas, and a second impurity gas which is a hydride of one of Group-III elements and Group-V elements; and wherein forming the poly-crystal silicon layer and forming the high-melting point metallic silicide layer are performed in the same chamber.
