    Abstract: A method and structure that provides a battery (420) within an integrated circuit for providing voltage to low-current electronic devices (900) that exist within the integrated circuit. The method includes Front-End-Of-Line (FEOL) processing for generating a layer of electronic devices (900) on a semiconductor wafer (402), followed by Back-End-Of-Line (BEOL) integration f or wires the electronic devices together to form completed electrical circuits of the integrated circuit. The BEOL integration includes forming a multilayered structure of wiring levels on the layer of electronic devices. Each wiring level includes conductive metallization (e.g., metal-plated vias, conductive wiring lines, etc.) embedded in insulative material. The battery (420) is formed during BEOL integration within one or more wiring levels, and the conductive metallization (432,434,442,444) conductively couples positive (42 4) and negative (422) terminals of the battery to the electronic devices (900). The battery (420) may have several different topologies relative to the structural and geometrical relationships among the battery electrodes and electrolyte. Multiple batteries may be formed within one or more wiring levels, and may be conductively coupled to the electronic devices. The multiple batteries may be connected in series or in parallel.
