Abstract:
To provide a semiconductor device including a low-loss optical waveguide. The optical waveguide included in the semiconductor device has a core layer covered with first and second clad layers having respectively different refractive indices. A portion of the core layer is covered at a first ratio, that is, a ratio of the first clad layer to the second clad layer and at the same time, a second ratio, that is, a ratio of the second clad layer to the first clad layer. At this time, the first ratio and the second ratio are each a finite value more than 0.

Claim (Index 20):
A semiconductor device, comprising:\n a core layer; a first clad layer having a refractive index lower than that of the core layer; and a second clad layer having a refractive index lower than that of the core layer and different from that of the first clad layer, wherein the core layer comprises: a first portion contiguous to the first clad layer and overlapping with the first clad layer in plan view; a second portion contiguous to the first clad layer, overlapping with the first clad layer in plan view, and adjacent to the first portion; and a third portion contiguous to the second clad layer, overlapping with the second clad layer in plan view, adjacent to the second portion, and having a finite radius of curvature, wherein the first clad layer contiguous to the second portion of the core layer and overlapping with the second portion of the core layer in plan view has, introduced therein, an impurity for having a refractive index different from that of the first clad layer contiguous to the first portion of the core layer and overlapping with the first portion of the core layer in plan view.
