Abstract
A method for manufacturing a light emitting diode (LED) die includes providing an LED die including a substrate, an N type semiconductor layer, an active layer, and a P type semiconductor layer grown on the substrate in sequence. The N type semiconductor layer, the active layer, and the P type semiconductor layer are etched to define a plurality of recesses and a groove. An insulating layer to cover side surfaces of the recesses and the P type semiconductor layer is formed and a portion of the insulating layer is etched to define an opening to expose a top portion of the P type semiconductor layer. A pair of electrodes is formed and the LED die is cut along the groove to obtain an individual LED die.
