  • Patent number: 9564286
    Abstract: Provided is a method of forming a thin film of a semiconductor device. The method includes forming a precursor layer on a surface of a substrate by supplying a precursor gas into a chamber, discharging the precursor gas remaining in the chamber to an outside of the chamber by supplying a purge gas into the chamber, supplying a reactant gas into the chamber, generating plasma based on the reactant gas, forming a thin film by a chemical reaction between plasma and the precursor layer and radiating extreme ultraviolet (EUV) light into the chamber, and discharging the reactant gas and the plasma remaining in the chamber by supplying a purge gas into the chamber.
    Type: Grant

  • Patent number: 8883266
    Abstract: A method of fabricating quantum confinements is provided. The method includes depositing, using a deposition apparatus, a material layer on a substrate, where the depositing includes irradiating the layer, before a cycle, during a cycle, and/or after a cycle of the deposition to alter nucleation of quantum confinements in the material layer to control a size and/or a shape of the quantum confinements. The quantum confinements can include quantum wells, nanowires, or quantum dots. The irradiation can be in-situ or ex-situ with respect to the deposition apparatus. The irradiation can include irradiation by photons, electrons, or ions. The deposition is can include atomic layer deposition, chemical vapor deposition, MOCVD, molecular beam epitaxy, evaporation, sputtering, or pulsed-laser deposition.

  • Patent number: 8524398
    Abstract: Improved energy storage is provided by exploiting two physical effects in combination. The first effect can be referred to as the All-Electron Battery (AEB) effect, and relates to the use of inclusions embedded in a dielectric structure between two electrodes of a capacitor. Electrons can tunnel through the dielectric between the electrodes and the inclusions, thereby increasing the charge storage density relative to a conventional capacitor. The second effect can be referred to as an area enhancement effect, and relates to the use of micro-structuring or nano-structuring on one or both of the electrodes to provide an enhanced interface area relative to the electrode geometrical area. Area enhancement is advantageous for reducing the self-discharge rate of the device.
