Light emitting diode (LED) die having strap layer and method of fabrication

摘要

A light emitting diode (LED) die includes a first-type semiconductor layer, a multiple quantum well (MQW) layer in electrical contact with the first-type semiconductor layer configured to emit electromagnetic radiation, and a second-type semiconductor layer in electrical contact with the multiple quantum well (MQW) layer. The light emitting diode (LED) die also includes a first pad in electrical contact with the first-type semiconductor layer, and a second pad in electrical contact with the second type semiconductor layer. The light emitting diode (LED) die also includes a strap layer having conductive straps and contact areas located in trenches in the first-type semiconductor layer.
