Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a first insulation film on the semiconductor substrate; a first resistance part on the first insulation film, the first resistance part being made of a conductive layer; a boundary film directly on the first resistance part; a second resistance part on a top surface of the boundary film, the second resistance part being made of a conductive layer; a second insulation film on the second resistance part; and a first conductive part and a second conductive part on the second insulation film, the first conductive part and the second conductive part being isolated from each other, wherein the first conductive part comprises a first connection part penetrating the second insulation film and the second resistance part and contacting a surface of the boundary film, the second conductive part comprises a second connection part penetrating the second insulation film and the second resistance part and contacting a surface of the boundary film, and the first resistance part is electrically connected to the first conductive part via the first connection part, and electrically connected to the second conductive part via the second connection part.
