  • Patent number: 7915725
    Abstract: Disclosed is a semiconductor silicon wafer having an electric power supply affixed to the backside of the wafer. By fabricating the electric power supply onto the backside of the wafer that has been left unused, the semiconductor chip can have a self-supplied power, realizing the self-powered semiconductor chip with an increased efficiency. Further, since the electric power supply is installed on the wafer, not the semiconductor chip, the fabrication procedure becomes very simple, and the battery can be mounted on any type of chip.
