PROCESS FOR GENERATING ELECTRICAL ENERGY IN A SEMICONDUCTOR DEVICE AND THE CORRESPONDING DEVICE

摘要

Electrical energy is generated in a device that includes an integrated circuit which produces thermal flux when operated. A substrate supports the integrated circuit. A structure is formed in the substrate, that structure having a semiconductor p-n junction thermally coupled to the integrated circuit. Responsive to the thermal flux produced by the integrated circuit, the structure generates electrical energy. The generated electrical energy may be stored for use by the integrated circuit.
