Abstract:
The present disclosure provides a chip packaging method and a package structure. The chip packaging method comprises: forming a protective layer having material properties on a die active surface of a die; attaching (such as adhering) the die in which the die active surface is formed with the protective layer onto a carrier, the die active surface facing the carrier, and a die back surface of the die facing away from the carrier; forming an encapsulation layer having material properties to encapsulate the die; removing (such as stripping off) the carrier to expose the protective layer; and forming a conductive layer and a dielectric layer. The chip packaging method reduces or eliminates warpage in the panel packaging process, lowers a requirement on an accuracy of aligning the die on the panel, reduces a difficulty in the panel packaging process, and makes the packaged chip structure more durable, and thus the present disclosure is especially suitable for large panel-level package and package of a thin chip with a large electric flux.
