Patent ID: 8890217

Claim:
An electronic device, comprising: an insulating substrate having an upper surface and a lower surface opposite to each other; a chip disposed above the upper surface of the insulating substrate, wherein the chip comprises a chip substrate, a semiconductor layer, and a plurality of conductive contacts, the semiconductor layer is located between the chip substrate and the conductive contacts, a thickness of the insulating substrate is 0.6 to 1 times a thickness of the chip substrate, and a specific surface area of the insulating substrate is greater than 1.1 times a specific surface area of the chip substrate; and a patterned conductive layer disposed between the upper surface of the insulating substrate and the chip, wherein the conductive contacts are directly connected to the patterned conductive layer, the chip is electrically connected to an external circuit via the patterned conductive layer, and heat generated by the chip is transferred to external surroundings via the patterned conductive layer and the insulating substrate.
