Abstract:
1. A package structure, comprising: a substrate having a first side and a second side opposite to the first side; a plurality of through-silicon-vias (TSVs) extending through the substrate from the first side to the second side; a first light-emitting diode (LED) die and a second LED die disposed over the first side of the substrate, wherein the first and second LED dies each include a multiple-quantum-well layer disposed between a p-type semiconductor layer and an n-type semiconductor layer; a dielectric isolation layer disposed over the first and second LED dies in a conformal manner; a first conductive interconnect element extending through the dielectric isolation layer and electrically coupling the n-type semiconductor layer of the first LED die through a first conductive pad to the p-type semiconductor layer of the second LED die through a second conductive pad, wherein one of the first and second conductive pads is disposed above a top surface of the multiple-quantum-well layer, and wherein the other one of the first and second conductive pads is disposed below a bottom surface of the multiple-quantum-well layer; and a second conductive interconnect element extending through the dielectric isolation layer and electrically coupling one of the first and second LED dies to at least one of the TSVs.
