Title:
LIGHT-EMITTING ELEMENT AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/084942
Kind Code:
A1
Abstract:
In the present invention, a semiconductor device comprises: a layered structure 20 in which a first compound semiconductor layer 21, an active layer 23 and a second compound semiconductor layer 22 are layered; a substrate 11; a first light-reflecting layer 41 disposed on a first surface side of the first compound semiconductor layer 21; and a second light-reflecting layer 42 disposed on a second surface side of the second semiconductor layer 22. The second light-reflecting layer 42 has a flat shape. A recessed surface section 12 is formed on a substrate surface 11b. The first light-reflecting layer 41 is formed at least on the recessed surface section 12. The first compound semiconductor layer 21 is formed over the recessed surface section 12 extending from the substrate surface 11b. A cavity is formed, above the recessed surface section 12, between the first light-reflecting layer 41 and the first compound semiconductor layer 21.
