Abstract:
The method of chip packaging comprises: S1: providing a carrier, and forming an adhesive layer on a surface of the carrier; S2: forming a first dielectric layer on a surface of the adhesive layer, and forming a plurality of first through holes corresponding to electrical leads of a semiconductor chip in the dielectric layer; S3: attaching the semiconductor chip with the front surface facing downwards to the surface of the first dielectric layer; S4: forming a plastic encapsulation layer covering the chip on the surface of the first dielectric layer; S5: separating the adhesive layer and the first dielectric layer to remove the carrier and the adhesive layer; and S6: forming a redistribution layer for the semiconductor chip based on the first dielectric layer and the first through holes.

Claim (Index 6):
The chip packaging method according to  claim 1 , characterized in that, the method for removing the adhesive layer from the first dielectric layer is selected from at least one of chemical etching, mechanical peeling, mechanical grinding, thermal baking, ultraviolet irradiation, laser ablation, chemical mechanical polishing, and wet stripping.
