Patent ID: 8809078

Claim:
A self-powered integrated circuit (IC) package, comprising: a substrate having opposing first and second main surfaces; an integrated circuit (IC) chip having opposing first and second main surfaces, the second main surface of the IC chip being mounted on the first main surface of the substrate; at least one first electrical interconnector that electrically couples the IC chip to the substrate; a solar cell having opposing first and second main surfaces, at least a portion of the first main surface of the solar cell being configured to receive light from an external source, the solar cell being configured to convert energy of the received light into electrical power; a plurality of second electrical interconnectors electrically coupling the solar cell to the first main surface of the substrate and thereby electrically connecting the solar cell to the IC chip via the substrate to supply the generated electrical power thereto, wherein the solar cell extends over the first main surface of the IC chip, and is mounted and electrically connected to the first main surface of the substrate with solder balls; and a mold compound disposed on the first main surface of the substrate and which encapsulates the IC chip, the at least one first electrical interconnector, and at least a portion of the solar cell.
