In a method of forming an adhesive layer for a blanket layer filling a contact hole in a semiconductor device, a Ti film, Ti-rich TiN film or a TiSix (x being 1.1 to 1.8) film is formed, and then a TiN (stoichiometric) film is formed. The Ti film, Ti-rich TiN film or TiSix is annealed to be converted into TiSi2 film. The formation of the Ti film, Ti-rich TiN film or a TiSix is performed by a continuous CVD process.
