Abstract

An integrated circuit system includes first and second device wafers, each having lateral sides along which a plurality of T-contacts are disposed. The first and second device wafers are stacked together and the lateral sides of the first and second device wafers are aligned such that each one of the plurality of T-contacts of the first device wafer is coupled to a corresponding one of the plurality of T-contacts of the second device wafer. A plurality of solder balls are attached to the lateral sides and are coupled to the plurality of T-contacts. A circuit board includes a recess with a plurality of contacts disposed along lateral sides within the recess. The first and second device wafers are attached to the circuit board such that each one of the plurality of solder balls provide a lateral coupling between the first and second device wafers and the circuit board.
