  • Patent number: 7829144
    Abstract: A method of forming a refractory metal film doped with III or V group elements. The first process gas is supplied from a first gas source through a first gas introducing member to and through a gas supply mechanism toward a substrate within a processing vessel. The second process gas is supplied from a second gas source through a second gas introducing member to and through the gas supply mechanism toward the substrate within the processing vessel. The processing vessel is purged by evacuating the processing vessel by an evacuating mechanism, while supplying the inert gas from a third source through a third gas introducing member to and through the gas supply mechanism into the processing vessel.

  • Publication number: 20090071404
    Abstract: A Ti film is formed by CVD in holes formed in an insulating film formed on a Si substrate or on a Si film formed on a Si substrate by a method according to the present invention. The method includes the steps of: loading a Si substrate into a film forming chamber; evacuating the chamber at a predetermined vacuum; supplying TiCl4 gas, H2 gas, Ar gas and SiH4 gas into the film forming chamber; and producing a plasma in the film forming chamber to deposit a Ti film in the holes formed in the insulating film. The Si substrate is heated at 500° C. or below during the deposition of the Ti film. The flow rate of the SiH4 gas is from 30 to 70% of the flow rate of the TiCl4 gas. This method enables formation of a Ti film on a Si base at positions of holes in an insulating layer, with a good morphology of the interface between the Si base and the Ti film and with a good step coverage.
