Abstract:
1. A film forming method for forming a titanium-containing film on an object, the method comprising: carrying the object into a processing chamber; pre-heating the object in the processing chamber to a film forming temperature while supplying a process gas containing an Ar gas and an H introducing a TiCl stopping the introducing of the TiCl forming a titanium film on the object by generating plasma of a process gas containing an Ar gas H exhausting the processing chamber while maintaining introduction of the Ar gas and the H pre-nitriding the titanium film under an atmosphere of a nitriding process gas consisting of the Ar gas, the H nitriding the pre-nitrided titanium film by applying a high-frequency power to generate plasma of a nitriding process gas consisting of the Ar gas, the H wherein a ratio of a quantity of flow of the NH
