Patent ID: 8421240

Claim:
A sensor device comprising: a substrate which includes an element forming region; a plurality of sensor elements arranged on a flexible part within the element forming region; a plurality of connection pads arranged on a region of the substrate other than the element forming region; a plurality of first upper layer wiring arranged at least on the flexible part within the element forming region and electrically connected with the plurality of sensor elements; a plurality of first lower layer wiring arranged on a lower layer than the plurality of first upper layer wiring on a region of the substrate other than the element forming region and electrically connected with the plurality of first upper layer wiring; a plurality of second lower layer wiring arranged on a same layer as the plurality of first lower layer wiring on a region of the substrate other than the element forming region and electrically connected with the plurality of connection pads; a plurality of second upper layer wiring arranged on a different layer from the plurality of first lower layer wiring and the plurality of second lower layer wiring and arranged to intersect with the plurality of first lower layer wiring and the plurality of second lower layer wiring; and an insulation layer arranged between the plurality of first lower layer wiring and the plurality of second lower layer wiring and the plurality of second upper layer wiring, and wherein a plurality of through holes are formed on the insulation layer in a position at which the plurality of first lower layer wiring and the plurality of second lower layer wiring intersect with the plurality of second upper layer wiring, and wherein the plurality of first upper layer wiring and the plurality of second upper layer wiring comprise metal material, and the plurality of first lower layer wiring and the plurality of second lower layer wiring comprise a semiconductor including diffused impurities.
