Abstract
Light emitting diode (LED) structures are fabricated in wafer scale by mounting singulated LED dies on a carrier wafer or a stretch film, separating the LED dies to create spaces between the LED dies, applying a reflective coating over the LED dies and in the spaces between the LED dies, and separating or breaking the reflective coating in the spaces between the LED dies such that some reflective coating remains on the lateral sides of the LED die. Portions of the reflective coating on the lateral sides of the LED dies may help to control edge emission.
