Patent ID: 7556869

Claim:
A semiconductor integrated circuit having a multilayered structure, comprising: a heat-generating element; and a CPP-CIC wiring for electrically connecting between a ground and said heat-generating element and/or between a power supply and said heat-generating element, wherein said CPP-CIC wiring comprises a columnar portion comprising thin films or layers layered in a direction perpendicular to planes of the films or layers, wherein a current flows along said columnar portion, and said CPP-CIC wiring functioning solely as a lead wire to a power supply and/or to the ground provides no electrically active function, wherein said CPP-CIC wiring includes a heat-generating interface and a heat-absorbing interface, the heat-absorbing interface being between different kinds of materials, wherein said different kinds of materials are selected from materials which produce a Peltier cooling effect at said heat-absorbing interface when a current flows therethrough, and a Peltier heating effect at said heat-generating interface when a current flows therethrough, and wherein said heat-absorbing interface is disposed such that the heat generated by said heat-generating element can be absorbed by said heat-absorbing interface.
