Abstract
Official abstract text for this publication.
A light emitting element having a recess-protrusion structure on a substrate is provided. A semiconductor light emitting element 100 has a light emitting structure of a semiconductor 20 on a first main surface of a substrate 10 . The first main surface of the substrate 10 has substrate protrusion portion 11 , the bottom surface 14 of each protrusion is wider than the top surface 13 thereof in a cross-section, or the top surface 13 is included in the bottom surface 14 in a top view of the substrate. The bottom surface 14 has an approximately polygonal shape, and the top surface 13 has an approximately circular or polygonal shape with more sides than that of the bottom surface 14.
First claim
Opening claim text (preview).
What is claimed is: 1. A semiconductor light emitting element, comprising: a substrate comprising at least one protrusion having a top surface and a bottom portion on a main surface of the substrate, and in cross-sections of the substrate, the bottom portion of the protrusion having a width greater than a width of the top surface of the protrusion, or in a top view of the substrate, an outline of the top surface being at an inner side of an outline of the bottom portion of the…
