Abstract:
1. A semiconductor device comprising: a base insulating film; a metal thin-film resistor that is provided on the base insulating film; a lower-layer insulating film that is formed under the base insulating film; and a wiring pattern that is formed on the lower-layer insulating film, wherein: the base insulating film is formed on the lower-layer insulating film and the wiring pattern, a connecting hole being formed in the base insulating film located on the wiring pattern; the metal thin-film resistor has at least two belt-like portions and a return portion that continues to the belt-like portions; the belt-like portions are located at a distance from the region on the wiring pattern; and the return portion connects the at least two belt-like portions in a position at a distance from the region on the wiring pattern, and is formed in the connecting hole via the region on the wiring pattern.
