Abstract:
The semiconductor device comprising:an electrode layer formed on a part of a semiconductor layer; a first insulating layer formed by covering said semiconductor layer and said electrode layer and by sequentially laminating a first insulating film and a first anti-reflection coating; a first contact hole formed in said first insulating layer and reaching said semiconductor layer by penetrating a vicinity of a side of said electrode layer from a surface of said first insulating layer; a first conductive plug embedded in said first contact hole and electrically connected to said semiconductor layer; a first wiring layer electrically connected to said semiconductor layer through said first conductive plug and formed on said first conductive plug; a second insulating layer formed by covering said first insulating layer and said first wiring layer; a second contact hole formed in said second insulating layer and reaching said first wiring layer and said first insulating layer from a surface of said second insulating layer; a second conductive plug embedded in said second contact hole and electrically connected to said first wiring layer; and a second wiring layer electrically connected to said first wiring layer through said second conductive plug and formed on said second conductive plug.
