Abstract: A method of fabricating a semiconductor device is provided. The method may include forming a first interlayer insulating film on a substrate, forming a second interlayer insulating film on the first interlayer insulating film, and forming a third interlayer insulating film on the second interlayer insulating film. Different amounts of carbon may be present in each of the first, second, and third interlayer insulating films. The third interlayer insulating film may be used as a mask pattern to form a via trench that extends at least partially into the first interlayer insulating film and the second interlayer insulating film. Supplying a carbon precursor may be interrupted between the forming of the second and third interlayer insulating films, such that the second interlayer insulating film and the third interlayer insulating film may have a discontinuous boundary therebetween.

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.
