Patent ID: 8642939

Claim:
A semiconductor device comprising at least: a first substrate that includes an imaging unit and a plurality of first electrodes on at least one or more surfaces; a second substrate that includes an image processing unit and a plurality of second electrodes on at least one or more surfaces; and a heat dissipating unit formed between the first electrodes and the second electrodes, wherein an electrical connection between the first electrodes and the second electrodes is formed when the first substrate is stacked on the second substrate, and wherein at least one of the first electrodes and the second electrodes are surrounded with insulative material, and wherein the heat dissipating unit is formed of conductive material, the heat dissipating unit has openings, in which the first or the second electrodes surrounded with insulative material are formed, formed at positions corresponding to each of the plurality of the first electrodes and the second electrodes and the plurality of the first electrodes of the first substrate and the plurality of the second electrodes on the second substrate are electrically connected.
