Assignee: TONGFU MICROELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A semiconductor package device, comprising:
a chip, wherein the chip includes:
a chip substrate having a front surface and a back surface, wherein the front surface includes a photosensitive region;
soldering pads disposed at the front surface of the chip substrate around the photosensitive region;
a metal part formed on each soldering pad; and
a transparent protective layer formed over the front surface of the chip substrate, wherein a top surface of the metal part protrudes, by a thickness, above a top surface of the transparent protective layer, wherein the transparent protective layer is formed by spin coating, dispensing, or printing a material and the transparent protective layer is a solidified material after ultraviolet irradiation or high-temperature baking;

a circuit board, at the back surface of the chip substrate; and
a conductive connection part, which electrically connects the metal part to the circuit board.
