It was confirmed that the uniformity of the film thickness distribution was increased. Further, when the coverage of the fine holes in the central portion and the outer peripheral portion of the substrate was confirmed by SEM photographs, it was confirmed that a highly dense Cu film could be formed over the entire inner surface of the fine holes.
