Abstract:
An improvement is achieved in the reliability of a semiconductor device. Over an insulating layer, an optical waveguide and a p-type semiconductor portion are formed. Over the p-type semiconductor portion, a multi-layer body including an n-type semiconductor portion and a cap layer is formed. Over a first interlayer insulating film covering the optical waveguide, the p-type semiconductor portion, and the multi-layer body, a heater located over the optical waveguide is formed. In the first interlayer insulating film, first and second contact holes are formed. A first contact portion electrically coupled with the p-type semiconductor portion is formed continuously in the first contact hole and over the first interlayer insulating film. A second contact portion electrically coupled with the cap layer is formed continuously in the second contact hole and over the first interlayer insulating film. A wire formed over a second interlayer insulating film is electrically coupled with the heater and the first and second contact portions via plugs embedded in the second interlayer insulating film.

Claim (Index 9):
The semiconductor device according to  claim 1 ,\n wherein the first interlayer insulating film is made of a multi-layer film including a first insulating film and a second insulating film, wherein the first insulating film is formed over the insulating layer such that the first insulating film covers the first optical waveguide and the first semiconductor portion, wherein the second semiconductor portion is formed in a third opening of the first insulating film which is formed over the first semiconductor portion, and wherein the second insulating film is formed over the first insulating film and over the second semiconductor portion.
