Abstract:
A semiconductor device including a first interlayer insulating film; a conductive pattern in the first interlayer insulating film; a resistance pattern on the conductive pattern; an upper etching stopper film spaced apart from the resistance pattern, extending in parallel with a top surface of the resistance pattern, and including a first metal; a lower etching stopper film on the conductive pattern, extending in parallel with a top surface of the first interlayer insulating film, and including a second metal; and a second interlayer insulating film on the upper etching stopper film and the lower etching stopper film, wherein a distance from a top surface of the second interlayer insulating film to a top surface of the upper etching stopper film is smaller than a distance from the top surface of the second interlayer insulating film to a top surface of the lower etching stopper film.
