Abstract:
1. A structure, comprising: a carrier substrate that includes a first contact pad and a second contact pad disposed over a first side of the carrier substrate and a third contact pad and a fourth contact pad disposed over a second side of the carrier substrate opposite the first side; a first epi-structure and a second epi-structure disposed over the carrier substrate, the first and second epi-structures eac including a first doped semiconductor layer, a second doped semiconductor layer having a different type of conductivity from the first doped semiconductor layer, and a light-emitting layer disposed between the first and second doped semiconductor layers respectively; a first metal element disposed between, and electrically coupling together, the first contact pad and the second doped semiconductor layer of the first epi-structure; a second metal element disposed between, and electrically coupling together, the second contact pad and the second doped semiconductor layer of the second epi-structure; and a first through-via and a second through-via that extend through the first and second epi-structures,respectively, wherein the first through-via electrically couples together the first doped semiconductor layer in the first epi-structure and the third contact pad; wherein the carrier substrate includes a substrate and an insulation film disposed between the substrate and the first, second, third and fourth contact pads.
