There is provided a semiconductor device which comprises a second insulating film (29) formed on a substantially flat surface, on which a surface of a first wiring (36) and a surface of a first insulating film (95) are continued, to cover the first wiring (36), a wiring trench (28a) formed in the second insulating film (29), connection holes (38a) formed in the second insulating film (29) to extend from the wiring trench (28a) to the first wiring (36), dummy connection holes (38b) formed in the second insulating film (29) to extend from the wiring trench (28a) to a non-forming region of the first wiring, and a second wiring (39) buried in the connection holes (38a) and the wiring trench (28a) to be connected electrically to the first wiring (36) and also buried in the dummy connection holes (38b), and formed such that a surface of the second wiring (39) and a surface of the second insulating film (29) constitute a substantially flat surface. <IMAGE> |
