Abstract:
A film forming apparatus comprising:a silicon film forming vacuum chamber for forming a crystalline silicon film on a substrate surface;an ion beam emission device provided in said vacuum chamber, for emitting an ion beam to said substrate surface;a film forming device provided in said vacuum chamber, for forming a pre-film on said substrate surface at an ion beam emission region;an energy beam irradiation device provided in said vacuum chamber for irradiating said pre-film with an energy beam, at an energy beam irradiation region, for crystallizing said pre-film; anda substrate transporting device arranged in said vacuum chamber for moving said substrate from the ion beam emission region to the energy beam irradiation region in such a way that the surface of such substrate having said pre-film formed on it, at the ion beam emission region, is able to pass through the energy beam irradiation region while pre-film is being formed on the surface of said substrate moving through the ion beam emission region.
