Patent ID: 7485933

Claim:
A semiconductor device comprising: a semiconductor substrate; a first insulating film formed on the semiconductor substrate; a plurality of resistors having the same shape and disposed on the first insulating film, each of the resistors being formed of a polycrystalline silicon film having a low concentration impurity region and high concentration impurity regions disposed on opposite sides of the low concentration impurity region, the low concentration impurity regions of the plurality of resistors having different lengths from one another; a second insulating film disposed on the plurality of resistors; a plurality of contact holes formed on the second insulating film and disposed on the high concentration impurity regions; first metal wirings connected to the respective contact holes and connecting the plurality of resistors in series; and a second metal wiring connected to one of the resistors located at one end of the plurality of resistors connected in series, the second metal wiring covering the low concentration impurity region of all of the plurality of resistors.
