The present disclosure provides a semiconductor packaging method and a semiconductor package device. The method includes providing a chip, where the chip includes a chip substrate having a front surface and a back surface; soldering pads disposed at the front surface of a 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. A first end of the metal part away from a corresponding soldering pad is in coplanar with the transparent protective layer; and the first end of the metal part is not covered by 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 to electrically connect the chip with the circuit board.

A method for fabricating silicon die stacks for electron emitter chips by applying sintering to bind a silicon substrate die to other die layers. Metal powder is applied to the bonding surface of the die, covered with the chip carrier or chip and compressed between two heated plates. The bonding pads of the die may be conductively coupled to corresponding bonding pads of the other die layers.
