Patent ID: 8598717

Claim:
A semiconductor device comprising: a plurality of semiconductor structures, each of the plurality of semiconductor structures comprising: a semiconductor chip; a connection electrode including a first land electrode electrically coupled with the semiconductor chip, and a cylindrical through electrode formed on an upper surface of the first land electrode that is electrically coupled to the first land electrode using a plurality of stud bumps wherein the plurality of stud bumps is formed between the through electrode and the land electrode wherein the diameter of the stud bumps is greater than the diameter of the cylindrical through electrode at the point at which the stud bumps and the cylindrical through electrode make contact; and a sealing resin, through which the connection electrode passes, for sealing the semiconductor chip, wherein the bottom surface of the land electrode is coplanar with the bottom surface of the sealing resin and wherein a top surface and portions of side surfaces of the through electrode extend above the top surface of the sealing resin.
