The surface morphology of an LED light emitting surface is changed by
applying a reactive ion etch (RIE) process to the light emitting surface.
Etched features, such as truncated pyramids, may be formed on the
emitting surface, prior to the RIE process, by cutting into the surface
using a saw blade or a masked etching technique. Sidewall cuts may also
be made in the emitting surface prior to the RIE process. A light
absorbing damaged layer of material associated with saw cutting is
removed by the RIE process. The surface morphology created by the RIE
process may be emulated using different, various combinations of non-RIE
processes such as grit sanding and deposition of a roughened layer of
material or particles followed by dry etching.
