  • Patent number: 12550776
    Abstract: The present invention provides a chip packaging structure and a chip packaging method. Compared with an existing method of joining an encapsulation layer with a dielectric layer, adhesion between the encapsulation layer and a chip in the present invention is increased, and the encapsulation layer is less likely to fall off under stress. Furthermore, during the packaging process, a passivation layer enables chips to be mutually fixed together, which can prevent the chips from being shifted during the encapsulation process, and thereby enhance the reliability of the final product and improve the yield of the final product.
