Abstract:
1. An apparatus for vacuum processing for use in forming an Ni film to be converted into a silicide film on the surface of a substrate mainly composed of Si, which comprises a film-forming chamber equipped with an exhaust system; a substrate-supporting stage equipped with a heating means and positioned at the lower portion of the film-forming chamber; a shower plate located above the substrate-supporting stage; a gas-introduction path for introducing a reducing gas into the film-forming chamber and a gas-introduction path for introducing, into the film-forming chamber, a raw gas for forming an Ni film consisting of a nickel alkylamidinate gas, these two gas-introduction paths being connected to the film-forming chamber directly; a canister for accommodating a precursor arranged in the course of the gas-introduction path for the introduction of the Ni film-forming raw gas; and a gas-introduction path for introducing an inert gas, which is connected to the canister for gasifying a liquefied precursor through the bubbling thereof and introducing the gasified precursor into the film-forming chamber and which is directly connected to the film-forming chamber, wherein the film-forming chamber is directly provided with a gas-supply path for supplying H
