Abstract

Official abstract text for this publication.

Solid state lighting dies and associated methods of manufacturing are disclosed herein. In one embodiment, a solid state lighting die includes a substrate material, a first semiconductor material, a second semiconductor material, and an active region between the first and second semiconductor materials. The second semiconductor material has a surface facing away from the substrate material. The solid state lighting die also includes a plurality of openings extending from the surface of the second semiconductor material toward the substrate material.

First claim

Opening claim text (preview).

We claim: 1. A method for forming a solid state lighting die, comprising: forming a buffer material on a substrate material; forming a masking material on the buffer material such that the buffer material is between the masking material and the substrate material, the masking material including a plurality of openings individually exposing a portion of the buffer material; removing the portion of the buffer material and a portion of the substrate material underlying the portion of the buffer material through the openings, thereby creating a plurality of indentations in the substrate material; depositing an insulating material into the indentations in the substrate material; and thereafter, forming an active region on the buffer material with the insulating material in the indentations. 2. The method of claim 1 , further comprising removing the masking material from the substrate material after the insulating material is deposited into the indentations. 3. The method of claim 1 wherein: the method further comprises removing the masking material from the substrate material after the insulating material is deposited into the indentations; and forming the active region includes forming a plurality of active elements separated from one another by the insulating material in the indentations.
