Abstract: In the course of a production of a semiconductor device with a multilayer insulating layer, when a contact hole is opened in the multilayer insulating layer, an insulating layer activating a metal selective vapor-growth appears at the side wall of the contact hole. A thin metal (e.g., tungsten) layer is selectively deposited in the contact hole. In another case, another metal layer appears within the contact hole. An insulating film preventing a metal selective vapor-growth is deposited over the whole surface of the side wall of the contact hole, the metal layer and a top surface of the multilayer insulating layer, and is anisotropically etched to leave a portion of the film lying on the side wall only as a side wall insulating film. The contact hole is completely filled with another metal (tungsten) by a selective vapor-growth method, to flatten an exposed surface, and then a conductor (e.g.
