Abstract:
An optical waveguide formed at the same layer as that of a microscopic optical device and a spot size converter largely different in size are integrally formed. A semiconductor device has an optical waveguide part functioning as a spot size converter. The optical waveguide part includes a plurality of optical waveguide bodies penetrating through an interlayer insulation layer in the thickness direction.

Claim (Index 14):
A method for manufacturing a semiconductor device, comprising the steps of:\n (a) providing a semiconductor wafer having a plurality of element formation regions formed of an insulation layer and a semiconductor layer formed over the insulation layer, and adjacent to one another; (b) patterning the semiconductor layer, and thereby forming an optical waveguide in each of the element formation regions; (c) forming a first interlayer insulation layer over the insulation layer in such a manner as to cover the optical waveguide; (d) forming a plurality of first through parts penetrating through the first interlayer insulation layer in the thickness direction, and separated from one another in the first interlayer insulation layer in each of the element formation regions; and (e) burying a film having a higher refractive index than the refractive index of the first interlayer insulation layer in each inside of the first through parts, and forming a first optical waveguide part capable of propagating a light through the inside thereof, wherein one end of the first optical waveguide part is arranged in such a manner as to cover one end of the optical waveguide, and wherein the other end of the first optical waveguide part includes a light receiving surface for receiving the light from the outside.
