ABSTRACT:
In a light emitting diode comprising a plurality of layers deposited on a substrate, the substrate is etched so as to reduce the area in which the substrate is attached to the plurality of layers. The reduction in the area of attachment results in less light being absorbed by the substrate and thus more total light shining forth from the light emitting diode.
