Abstract
A light emitting diode (LED) device includes a semiconductor layer and one or more portions of a wafer on which the semiconductor layer was formed, the other portions of the wafer having been removed by an etching process. The semiconductor layer has a front surface that includes a light emitting area. The remnants of the wafer on which the semiconductor layer are disposed on the front surface of the semiconductor layer and define a trench. The trench is positioned such that the light emitting area emits light into the trench. The remnants of the wafer make the LED device more robust and the trench may reduce crosstalk with adjacent LED devices.
