A worktable device is disposed inside a film formation process container for a semiconductor process. The worktable device includes a worktable including a top surface to place a target substrate thereon, and a side surface extending downward from the top surface, and a heater disposed in the worktable and configured to heat the substrate through the top surface. A CVD pre-coat layer covers the top surface and the side surface of the worktable. The pre-coat layer has a thickness not less than a thickness which substantially saturates the amount of radiant heat originating from heating of the heater and radiated from the top surface and the side surface of the worktable.

In a process of forming a metal film, when metal wiring is formed on a diffusion layer (an electrode, etc.) of a circuit element formed on a silicon semiconductor wafer, a Ti film is deposited on a surface of a processed body by PECVD using TiCl.sub.4 gas and H.sub.2 gas as material gas. A Ti--Si--N film is formed on the diffusion layer surface by adding N.sub.2 gas to the material gas, and the Ti film is formed subsequently on the Ti--Si--N film. The Ti--Si--N film suppresses diffusion of silicon from the semiconductor wafer side.

A Ti film is formed on a surface of a wafer W placed inside a chamber 31, while injecting a process gas containing TiCl4 gas into the chamber 31 from a showerhead 40 made of an Ni-containing material at least at a surface. The method includes performing formation of a Ti film on a predetermined number of wafers W while setting the showerhead 40 at a temperature of 300° C. or more and less than 450° C., and setting TiCl4 gas at a flow rate of 1 to 12 mL/min (sccm) or setting TiCl4 gas at a partial pressure of 0.1 to 2.5 Pa, and then, performing cleaning inside the chamber 31, while setting the showerhead 40 at a temperature of 200 to 300° C., and supplying ClF3 gas into the chamber 31.

A cleaning process is performed on the surface of a nickel silicide film serving as an underlayer. Then, a Ti film is formed to have a film thickness of not less than 2 nm but less than 10 nm by CVD using a Ti compound gas. Then, the Ti film is nitrided. Then, a TiN film is formed on the Ti film thus nitrided, by CVD using a Ti compound gas and a gas containing N and H.

A film formation method to form a predetermined thin film on a target substrate includes first and second steps alternately performed each at least once. The first step is arranged to generate first plasma within a process chamber that accommodates the substrate while supplying a compound gas containing a component of the thin film and a reducing gas into the process chamber. The second step is arranged to generate second plasma within the process chamber while supplying the reducing gas into the process chamber, subsequently to the first step.

The invention relates to a gas supplying unit to be arranged to hermetically fit in an opening formed at a ceiling part of a processing container for conducting a process to a substrate. The gas supplying unit includes a plurality of nickel members. A large number of gas-supplying holes is formed at a lower surface of the gas supplying unit, a process gas is adapted to be supplied from the large number of gas-supplying holes into the processing container, and the plurality of nickel members is fixed to each other via an intermediate member for preventing sticking made of a material different from nickel.
