1. A method comprising:
- disposing a supporting material onto a surface of a first package component, wherein the first package component comprises a plurality of electrical connectors on the surface, wherein the plurality of electrical connectors is adjacent to peripheral regions of the first package component, and wherein the supporting material is adjacent to a center region of the surface;
after the supporting material is disposed, bonding the first package component to a second package component through the plurality of electrical connectors, with the supporting material disposed between the first package component and the second package component; and
encapsulating the supporting material and the plurality of electrical connectors in an encapsulating material, wherein the supporting material and the encapsulating material are different from each other.
