  • Patent number: 7785733
    Abstract: A battery having an electrode with at least one nanostructured surface is disclosed wherein the nanostructured surface is divided into cells and is disposed in a way such that an electrolyte fluid of the battery is prevented from contacting the portion of electrode associated with each cell. When a voltage is passed over the nanostructured surface associated with a particular cell, the electrolyte fluid is caused to penetrate the nanostructured surface of that cell and to contact the electrode, thus activating the portion of the battery associated with that cell. The current/voltage generated by the battery is controlled by selectively activating only a portion of the cells. Multiple cells can be active simultaneously to produce the desired voltage. The more cells that are active, the higher the current/voltage and the lower the overall life of the battery. The life of the battery can be extended by activating fewer cells simultaneously.

  • Patent number: 7785753
    Abstract: Disclosed is a method for processing a two layer mask for use in fabrication of semiconductor devices whereby the critical dimension (CD) of a semiconductor device being fabricated with the mask can be controlled. After forming a carbon mask layer and a silicon containing photoresist layer on the carbon mask, a two-step process forms openings in the carbon mask layer, as required for subsequent device fabrication. The structure is placed in a plasma processing chamber, and an oxygen plasma is employed to partially etch the carbon layer. The oxygen plasma reacts with silicon in the photoresist to form a hard silicon oxide layer on the surface of the photoresist. A hydrogen plasma is then employed to complete the etch through the carbon layer with a reduced critical dimension. Damage to the silicon containing photoresist layer is kept to a minimum during the plasma etch process by limiting the low frequency RF power.
