Abstract:
The present invention provides the technology for burying metal even in a fine concave portion such as trench and via. According to an embodiment of the present invention, a vapor of the metal as the objective material, a gas containing halogen for etching the metal, and a metal halide vapor made up of the metal element and the halogen element are supplied to the substrate, which thus forms a metal halide layer in the concave portion, and thereby deposits the metal under the metal halide layer. The procedure can achieve the above object.
