Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device capable of improving covering capability of a protective film for protecting metal wiring.SOLUTION: When wiring width of a bent part 16 of metal wiring 14 is increased, coating width of resist for patterning the wiring is increased. When the coating width of the resist is increased, the quantity of the resist is increased, and the tapered shape of a resist profile is intensified (the slope of a side face becomes gentle). Thus, the tapered shape of the side face (metal etching shape) of the patterned metal wiring 14 is intensified (the slope of the side face becomes gentle), and thereby the thickness of a passivation protective film covering the bent part 16 is increased. Thus, covering capability of the protective film for protecting the metal wiring can be improved.
