Claim:
1. A method comprising: epitaxially growing a light emitting structure on a growth surface of a substrate; scribing the substrate to form a first widening angled side surface, wherein the first widening angled side surface extends from the growth surface of the substrate on which the light emitting structure is grown, wherein the first widening angled side surface forms a first angle with a negative of a normal vector of the growth surface of the substrate that is approximately thirty degrees, and wherein the first widening angled side surface causes at least a portion of the substrate to widen in a direction away from the light emitting structure; forming a second widening angled side surface on the light emitting structure, wherein the second widening angled side surface forms a second angle with the normal vector of the growth surface of the substrate, wherein the first angle and the second angle are different; and cleaning the substrate and the light emitting structure after the scribing and the forming.
