Abstract:
1. A semiconductor device comprising: a semiconductor substrate including a semiconductor region surrounded with by an element isolation region; a first insulating film formed on the semiconductor region; a pair of resistance elements located at the semiconductor region, each of the resistance elements including a first conductive film formed on the first insulating film, a second insulating film formed on the first conductive film and a second conductive film formed on the second insulating film; a pair of first contact plugs formed on one of the resistance elements, the first contact plugs being arranged along a first direction relative to the semiconductor region; and a pair of second contact plugs formed on the other of the resistance elements, the second contact plugs being arranged along the first direction, wherein one of the resistance elements has a first width in a second direction which is perpendicular to the first direction, and the semiconductor region has a second width in the second direction, the first width being smaller than half of the second width; the second insulating films of the resistance elements are spaced from each other by a first distance in the second direction; and the second conductive films of the resistance elements are spaced from each other by a second distance in the second direction, the second distance being longer than the first distance.
