  • Patent number: 9484155
    Abstract: A thin, rechargeable, flexible electrochemical energy cell includes a battery cell, or a capacitor cell, or a battery/capacitor hybrid cell that can be stackable in any number and order. The cell can be based on a powdery mixture of hydrated ruthenium oxide particles or nanoparticles with activated carbon particles or nanoparticles suspended in an electrolyte. The electrolyte may contain ethylene glycol, boric acid, citric acid, ammonium hydroxide, organic acids, phosphoric acid, and/or sulphuric acid. An anode electrode may be formed with a thin layer of oxidizable metal (Zn, Al, or Pb). The cathode may be formed with a graphite backing foil. The energy cell may have a voltage at or below 1.25V for recharging. The thickness 15 of the cell structure can be in the range of 0.5 mm-1 mm, or lower.

  • Patent number: 8054450
    Abstract: A stepper system for ultra-high resolution nano-lithography employs a photolithographic mask which includes a layer of an electrically conductive optically opaque material in which periodic arrays of sub-wavelength apertures are formed. The plasmonic excitation in the photolithographic mask exposed to the light of the wavelength in the range of 197 nm-248 nm, produces high resolution far-field radiation patterns of sufficient intensity to expose a photoresist on a wafer. The stepper system demonstrates the resiliency to the mask defects and ability to imprint coherent clear features of nano dimensions (45 nm-500 nm) and various shapes on the wafers for integrated circuits design. The stepper system may be adjusted to image the plane of the highest plasmonic field exiting the mask.

  • Patent number: 8052908
    Abstract: A nanophotolithography mask includes a layer of an electrically conductive optically opaque material deposited on a mask substrate in which regular arrays of sub-wavelength apertures are formed. The plasmonic excitation in the layer perforated with the sub-wavelength apertures arrays under the light incident on the mask produces high resolution far-field radiation patterns of sufficient intensity to expose a photoresist on a wafer when propagated to the same. The fill-factor of the mask, i.e., the ratio of the total apertures area to the total mask area, may lead to a significant increase in mask manufacturing throughput by FIB or electron beam “writing”. The mask demonstrates the defect resiliency and ability to imprint coherent clear features of nano dimensions and shapes on the wafers for integrated circuits design.
