Abstract
Embodiments relate to a method for fabricating a light-emitting-diode (LED). A metal layer is deposited on a p-type semiconductor. The p-type semiconductor is on an n-type semiconductor. The metal layer is patterned to define a p-metal. The p-type semiconductor is etched using the p-metal as an etch mask. Similarly, the n-type semiconductor is etched using the p-metal and the p-type semiconductor as an etch mask to define individual LEDs.
