Patent ID: 8778704

Claim:
A self-powered integrated circuit (IC) device, comprising: a lead frame having opposing first and second main surfaces, a chip support area with a center opening and a plurality of leads surrounding the chip support area; a solar cell having opposing first and second main surfaces, wherein at least a portion of the first main surface of the solar cell is configured to receive light from an external source and the second main surface of the solar cell is attached to the chip support area of the first main surface of the lead frame with a portion of the second main surface of the solar cell exposed through the center opening of the chip support area, wherein the solar cell converts energy of the received light into electrical power; an integrated circuit (IC) chip having opposing first and second main surfaces, the first main surface of the IC chip being mounted on the second main surface of the solar cell through the center opening of the chip support area, wherein the IC chip is electrically connected to the solar cell through the center opening to receive the electrical power generated by the solar cell; at least one first electrical interconnector electrically connecting the leads of the lead frame with the IC chip; and a first encapsulant that covers at least a portion of the lead frame, the IC chip, the at least one first electrical interconnector, and at least a portion of the solar cell.
