摘要： A method of forming wiring of a semiconductor device includes: forming an insulating resin on a main surface of a substrate such that an opening portion defining a wiring pattern is provided in the insulating resin; forming a first wiring layer made of a first metal on a bottom surface and side surfaces of the opening portion surrounding and a surface of the insulating resin opposite to the main surface of the substrate, the first wiring layer having a bottom portion formed on the bottom surface of the opening portion and side portions formed on the side surfaces, the bottom portion having a thickness greater than a thickness of at least one of the side portions; and cutting the insulating resin and the first wiring layer such that the insulating resin and the first wiring layer are exposed.
