Abstract:
A package includes a substrate, an Under-Bump Metallurgy (UBM) penetrating through the substrate, a solder region over and contacting the UBM, and an interconnect structure underlying the substrate. The interconnect structure is electrically coupled to the solder region through the UBM. A device die is underlying and bonded to the interconnect structure. The device die is electrically coupled to the solder region through the UBM and the interconnect structure. An encapsulating material encapsulates the device die therein.

Claim (Index 1):
A method comprising:\n bonding a device die to a wafer, wherein the wafer comprises a substrate and an interconnect structure; thinning the substrate; etching the substrate to form an opening in the substrate, wherein a metal pad in the interconnect structure is exposed through the opening; forming a polymer layer to cover the substrate, wherein the polymer layer extends into the opening to cover the metal pad; patterning the polymer layer to expose the metal pad; and forming a metal feature overlying the polymer layer, wherein the metal feature extends into the opening to contact the metal pad.
