A method for fabricating a semiconductor device according to the present invention includes: a step for forming a wiring layer on a semiconductor substrate; a step for patterning the wiring layer; and a step for covering the wiring layer with a protective insulating film. Moreover, after the step for forming the wiring layer, all required heat treatment steps to be performed prior to the step for covering the wiring layer with the protective insulating film are performed at a temperature lower than a temperature for plastic deformation of the wiring layer.
