LIGHT EMITTING DIODE(LED)DIE HAVING STEPPED SUBSTRATES AND METHOD OF FABRICATION

摘要

A light emitting diode (LED) die includes a first substrate having a first surface and an opposing second surface; a second substrate on the second surface of the first substrate; a p-type semiconductor layer on the first surface of the first substrate; a multiple quantum well (MQW) layer on the p-type semiconductor layer configured to emit light; and an n-type semiconductor layer on the multiple quantum well (MQW) layer.
