Abstract
Disclosed herein are techniques for reducing the pitch between light-emitting diodes (LEDs) in an array of LEDs. According to an aspect of the invention, a method includes forming a plurality of stacks of layers on a surface of a semiconductor, with a p contact at an interface between each stack and a p-type layer of the semiconductor. The semiconductor is etched to form a plurality of mesa shapes corresponding to the plurality of stacks. A dielectric is formed on at least a portion of each mesa shape and at least a portion of each stack. A reflector is formed on at least a portion of the dielectric and at least a portion of the semiconductor to provide an n contact at an interface between the reflector and an n-type layer of the semiconductor. The reflector is physically separated from the p contact for each stack.
