Abstract
There is formed a semiconductor device including, as the uppermost-layer wiring of the multilayer wiring layer, a plurality of first wirings, a second wiring, a plurality of first dummy wirings, a second dummy wiring, and a passivation film covering these wirings. The passivation film is patterned by etching with a photoresist film used as a mask, the plurality of first wirings and the plurality of first dummy wirings close thereto are densely formed, and the second dummy wiring is formed so as to surround a periphery of the second wiring sparsely formed directly above an analog circuit portion.
