    Abstract: It is intended to form a metallic film with resistance lower than in the prior art through controlling of crystal structure. The method may comprise the first tungsten film forming step and the second tungsten film forming step. In the first tungsten film forming step, the step of feeding, for example, WF6 gas as a metallic raw material gas and the step of feeding, for example,SiH4 gas as a hydrogen compound gas are alternately repeatedly carried out with the purging step of feeding an inert gas, for example, Ar gas or N2 gas interposed between the above steps to thereby form the first tungsten film containing amorphous matter. In the second tungsten film forming step, the WF6 gas and a reducing gas, for example, H 2 gas are simultaneously fed over the first tungsten film so as to form the second tungsten film. The ratio of amorphous matter contained in the first tungsten film is controlled by varying the execution time of the purging step ensuing the step of feeding SiH4 gas. ® KIPO & WIPO 2008

    Abstract: A method of forming a tungsten film, capable of restricting voids and volcanoes as large as adversely affecting characteristics despite the small diameter of a buried hole, and providing good burying characteristics. When forming a tungsten film on the surface of an object of treating (W) in a vacuumizing-enabled treating vessel (22), a reduction gas supplying process (70) and a tungsten gas supplying process (72) for supplying a tungsten-containing gas are alternately repeated with a purge process (74), for supplying an inert gas while vacuumizing, intervened therebetween to thereby form an initial tungsten film (76). Therefore, an initial tungsten film can be formed as a nucleation layer high in film thickness uniformity; and, accordingly, when main tungsten films are subsequently deposited, it is possible to restrict voids and volcanoes as large as adversely affecting characteristics despite the small diameter of a buried hole, and provide good burying characteristics.
