Patent ID: 8093701

Claim:
An electronic device including: a plurality of semiconductor devices, wherein each of said plurality of semiconductor devices comprises: a substrate including a front surface, a circuit element part on said front surface having electrode portions, and a rear surface opposite said front surface; an insulating material extending outwardly from peripheral portions of the substrate, the insulating material having through holes outside each of the peripheral portions of the substrate, each of the through holes having a top opening and a bottom opening opposite the top opening; metal wiring patterns extending from the electrode portions to inside said through holes, respectively; and a conductive material in each of said through holes; wherein one part of the conductive material protrudes from the top opening of each of the through holes and is located above the front surface of the substrate in a cross-sectional view, and another part of the conductive material protrudes from the bottom opening of each of the through holes and is located below the rear surface of the substrate in a cross-sectional view; and wherein said plurality of semiconductor devices are laminated such that vertically adjacent conductive materials are directly connected with each other.
