Japanese Patent JP7444067
Kind Code:
B2
Abstract:
A semiconductor device comprising: a layered structure 20 configured by layering a first compound semiconductor layer 21, an active layer 23, and a second compound semiconductor layer 22; a substrate 11; a first light reflecting layer 41 arranged on the first surface side of the first compound semiconductor layer 21; and a second light reflecting layer 42 arranged on the second surface side of the second compound semiconductor layer 22, wherein the second light reflecting layer 42 has a flat shape; a concave surface portion 12 is formed on a substrate surface 11b; the first light reflecting layer 41 is formed on at least the concave surface portion 12; the first compound semiconductor layer 21 is formed to extend from the substrate surface 11b onto the concave surface portion 12; and a cavity is present between the first light reflecting layer 41 formed on the concave surface portion 12 and the first compound semiconductor layer 21.
