摘要:
The object of the invention is to provide such a highly reliable semiconductor device as no defect such as the breakage of a tungsten conductor occurs. This object is achieved by the following means, i.e., a molybdenum film, a tungsten film and another molybdenum film are deposited in this order on an interlayer dielectric film formed on a silicon substrate.
