For forming electrical interlayer contact in a semiconductor device, an insulating film is formed on a first electrically conductive layer and then a contact hole is formed in the insulating film to expose a part of the first electroconductive, an activated surface of the exposed part is formed in the contact hole, a gas containing an impurity component is supplied to form an impurity adsorption film on the activated surface, and the contact hole is filled with a second electrically conductive layer which electrically contacts the first layer through the contact hole.
