Patent ID: 8058669

Claim:
A circuit structure comprising: a carrier substrate comprising: a first, a second, and a third through-via, wherein each of the first, the second, and the third through-vias extends from a first surface of the carrier substrate to a second surface of the carrier substrate opposite the first surface; a first and a second contact pad on the first surface of the carrier substrate; and a third and a fourth contact pad on the second surface of the carrier substrate, wherein the third contact pad is electrically connected to the first contact pad through the first and the second through-vias, and the fourth contact pad is electrically connected to the second contact pad through the third through-via; a light-emitting diode (LED) chip bonded onto the first surface of the carrier substrate, wherein the LED chip comprises a first electrode and a second electrode connected to the first contact pad and the second contact pad, respectively; and electrical connections on the second surface of the carrier substrate and connecting the first and second through-vias to a circuit comprising other electronic devices.
