Abstract:
An object of the present invention is to reduce the manufacturing cost of a semiconductor device. A semiconductor device includes a SOI substrate that has an optical waveguide including a semiconductor layer. The optical waveguide is covered with an interlayer insulating film. Wiring parts are formed on the interlayer insulating film. Moreover, a thin film part having a smaller thickness than the wiring parts is formed above the optical waveguide and is integrated with the wiring parts.

Claim (Index 10):
A method of manufacturing a semiconductor device, comprising:\n (a) preparing a semiconductor substrate including a substrate, a first insulating film formed over the substrate, and a semiconductor layer formed over the first insulating film; (b) forming an optical waveguide including the semiconductor layer over the first insulating film by patterning the semiconductor layer; (c) forming a second insulating film covering the optical waveguide over the first insulating film; (d) forming a first groove and a second groove deeper than the first groove over the second insulating film; (e) after the (d), sequentially forming a barrier film and a conductive film over the second insulating film; and (f) removing the conductive film and the barrier film outside the first groove and the second groove to form a wiring part in the second groove and form a thin film part having a smaller thickness than the wiring part in the first groove, the thin film part being integrated with the wiring part, wherein the first groove is arranged above the optical waveguide.
