Field of the Invention The present invention generally relates to a method for forming a silicon nitride film for use in a semiconductor device, and more particularly to a method for forming a silicon nitride film for use in a semiconductor device by plasma-enhanced CVD. 2. Description of the Related Art In recent years, a dual damascene process is widely used in the formation of copper wiring or copper contact. In this process, a fine tungsten (W) wiring or a contact is formed inside a dielectric film, and then a barrier layer is formed inside the fine tungsten wiring or contact in order to prevent mutual diffusion of copper with the dielectric film. As a method for forming such a barrier layer, a method for forming a silicon nitride film by plasma-enhanced CVD is widely used. For example, Japanese Patent Laid-Open No. 2000-147769 (Patent Document 1) discloses a method for forming a silicon nitride film by plasma-enhanced CVD using silane and ammonia (NH3). In this method, after a gate electrode is formed, a barrier layer is formed using a silicon nitride film formed by this method. Japanese Patent Laid-Open No. 2004-257194 (Patent Document 2) discloses a method for forming a silicon nitride film by plasma-enhanced CVD using silane and nitrous oxide (N2O). In this method, after a gate electrode is formed, a barrier layer is formed using a silicon nitride film formed by this method. However, according to the method disclosed in the Patent Document 1, there is a problem that since the substrate is heated to 550° C. or higher during the formation of the silicon nitride film, the copper wiring is likely to be oxidized. In the method disclosed in the Patent Document 2, there is a problem that a ratio of partial pressure of silane is excessively high during the formation of the silicon nitride film, and the amount of copper to be oxidized is increased.[Lactobacillus casei bacteria do
