Claim Text:
1. A device, comprising: a first substrate having a land disposed on a first surface, the land having a bottommost surface lower than a topmost surface of the first substrate; a stud disposed on the land; a protective layer disposed over the first surface of the first substrate and around the stud, the protective layer having a substantially planar top surface that is substantially coplanar with a top surface of the stud; a post-passivation interconnect (PPI) disposed over the protective layer and in electrical contact with the stud, a first portion of the PPI extending laterally from the stud; an interconnect disposed on and in electrical contact with the first portion of the PPI; a molding compound covering the PPI and partially covering the interconnect, wherein the molding compound has a bottommost surface that directly contacts a topmost surface of the protective layer and a topmost surface of the PPI and the molding compound has a topmost surface that extends to about halfway up the interconnect, and wherein the molding compound is a single homogenous material from the bottommost surface to the topmost surface; and a second substrate mounted on the interconnect.
