The semiconductor device of the present invention comprises an optical transmission
region, and a light receiving part for converting light propagating through the
optical transmission region to an electrical signal, wherein the optical transmission
region comprises a two-dimensional optical waveguide layer, and wherein at least
a portion of the light receiving part is embedded in the optical transmission region,
whereby the present invention can provide a semiconductor device having reduced
direction dependency when light propagating through the optical transmission region
is received.
