Abstract

A light emitting diode (LED) structure comprises a first dopant region, a dielectric layer on top of the first dopant region, a bond pad layer on top of a first portion the dielectric layer, and an LED layer having a first LED region and a second LED region. The bond pad layer is electrically connected to the first dopant region. The first LED region is electrically connected to the bond pad layer.
