Abstract

The present disclosure provides a semiconductor packaging method and a semiconductor package device. The semiconductor packaging method includes providing a chip, where the chip includes a chip substrate having a front surface and a back surface, where the front surface includes a photosensitive region; soldering pads disposed at the front surface of the chip substrate surrounding the photosensitive region; a metal part formed on a side of each soldering pad facing away from the chip substrate; and a transparent protective layer formed on the front surface of the chip substrate, where a first end of the metal part is exposed by protruding over a surface of the transparent protective layer. The method further includes electrically connecting the first end of the metal part to a circuit board using a conductive connection part, such that the chip is electrically connected to the circuit board.
