<P>PROBLEM TO BE SOLVED: To provide a light emitting element wherein the luminescent flux directed toward the substrate is also derived outward for a great improvement in light extraction efficiency by using as a part of the element the light absorbing compound semiconductor substrate for growing a light emitting layer section thereon. <P>SOLUTION: In the light emitting element 100, a compound semiconductor layer 40 having a light emitting layer 24 is epitaxially grown on the first main surface of a light absorbing compound semiconductor substrate. A light extraction plane EA is formed on the first main surface side of the compound semiconductor layer 40, and a light extraction electrode 9 is formed to partially cover the light extraction plane EA. At least a part just under the light extraction plane EA is a target to be notched, and a notch 1j is formed in the light absorbing compound semiconductor substrate so that at least a part of the region just under the light extraction electrode 9 is included in a residual substrate 1, resulting from notch formation. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
