Abstract
A semiconductor device equipped with a metal thin film resistor is disclosed. The semiconductor device includes a second interlayer insulating film formed on a first interlayer insulating film including a formation area of a wiring pattern. Connecting holes are formed in the second interlayer insulating film corresponding to both ends of the metal thin film resistor and the wiring pattern. An upper part of each connecting hole is formed in a taper shape. A sidewall is formed on the inner wall of each connecting hole. The metal thin film resistor is formed on the second interlayer insulating film between the connecting holes, inside of each connecting hole, and on the wiring pattern.
