Abstract: The method includes the steps of forming an insulating layer (2) to be thinner than a half of the metallic wiring film width (W) in thickness on the lower layer (1), patterning the layer (2) to form a metallic wiring pattern, forming a metallic layer (3) to pattern the metallic layer (3), until the patterned film (2') is exposed, to form a metallic wiring film (3'), and forming a second insulating film (4). The method improves the insulating characteristic and planarization.
