Patent ID: 8796782

Claim:
A semiconductor device comprising, in the main surface of a semiconductor substrate: an element isolation insulating film formed in a predetermined region; an element forming region defined by the element isolation insulating film; a field effect transistor including a pair of source/drain regions and a gate electrode formed in the element forming region; a resistance element situated over the element isolation insulating film formed of a polysilicon film, and having a resistor main body having a predetermined impurity concentration and a contact region; and a shielding film covering at least the resistor main body and comprising a first insulating film and a second insulating film formed over the first insulating film, wherein the first insulating film of the shielding film has: a first portion situated on the lateral side of the polysilicon film of the resistance element; and a second portion extending from the lateral side in a direction apart from the lateral side along the upper surface of the element isolation insulating film, wherein the second insulating film of the shielding film is situated so as to cover the first portion and the second portion of the first insulating film, and wherein the field effect transistor comprises a side wall insulating film formed of a layer identical with that of the second insulating film, directly contacting a side wall of the gate electrode.
