  • Publication number: 20190081480
    Abstract: A clean-energy power supply system is coupled between a power supply and a load. A first power generation device is configured to provide a renewable voltage. A power transformation device transforms the renewable voltage according to a first selection signal to generate a first transformed voltage or a second transformed voltage. A switch selectively transmits the first transformed voltage and the external voltage provided by the power supply to the load or transmits the second transformed voltage to the load. When the external voltage is not less than a predetermined value, the power transformation device generates the first transformed voltage and the switch transmits the first transformed voltage and the external voltage. When the external voltage is less than the predetermined value, the power transformation device stops generating the first transformed voltage and generates the second transformed voltage and the switch transmits the second transformed voltage.

    Abstract: A method for forming a cell contact. A substrate having first and second protruding structures is prepared. An etch stop layer is deposited over the substrate. A sacrificial layer is deposited on the etch stop layer. The sacrificial layer is recessed. Spacers are formed on the top surface of the sacrificial layer. A portion of the sacrificial layer not covered by the spacers is etched away, thereby forming a recess. A gap filling material layer is deposited into the recess. An upper portion of the gap filling material layer and the spacers are removed to expose the top surface of the sacrificial layer. The sacrificial layer is removed to form contact holes. A punch etching process is performed to remove the etch stop layer from bottoms of the contact holes. The contact holes is filled up with a conductive material layer.
