Abstract:
A light emitting diode is disclosed, together with associated wafer structures, and fabrication and mapping techniques. The diode includes an active portion, a raised border on the top surface of the active portion and around the perimeter of the top surface of the active portion, a resin in the space defined by the border and the top surface of the active portion, and phosphor particles in the resin that convert the frequencies emitted by the active portion.
