Abstract:
1. An apparatus to provide optical power to a semiconductor, the apparatus comprising: an active semiconductor layer of a semiconductor chip, the active semiconductor layer disposed toward a front side of the semiconductor chip, the active semiconductor layer comprising one or more integrated circuit devices; a photovoltaic semiconductor layer of the semiconductor chip, the photovoltaic semiconductor layer disposed between the active semiconductor layer and a back side of the semiconductor chip, the back side of the semiconductor chip opposite the front side of the semiconductor chip, the photovoltaic semiconductor layer converting electromagnetic radiation to electric power; one or more conductive pathways between the photovoltaic semiconductor layer and the active semiconductor layer; and one or more positive polarity electrical conductors disposed between the photovoltaic semiconductor layer and the active semiconductor layer and one or more negative polarity electrical conductors disposed on an opposite side of the photovoltaic semiconductor layer as the one or more positive polarity electrical conductors, the one or more conductive pathways in electrical communication with the one or more positive polarity electrical conductors and the one or more negative polarity electrical conductors to provide the electric power from the photovoltaic semiconductor layer to the integrated circuit devices of the active semiconductor layer.
