  • Patent number: 9007694
    Abstract: A display apparatus including a display unit, a first reflector, a second reflector, a third reflector and a lens unit is provided. The display unit emits an image beam. The first reflector is disposed on a transmission path of the image beam. The second reflector is disposed on the transmission path of the image beam from the first reflector. The third reflector is disposed on the transmission path of the image beam from the second reflector. The lens unit is disposed on the transmission path of the image beam from the third reflector. The image beam emitted from the display unit passes through a space defined between the second reflector and the third reflector and is transmitted to the first reflector. Afterward, the image beam is sequentially reflected by the first reflector, the second reflector and the third reflector, and then passes through the lens unit.

  • Patent number: 8962466
    Abstract: A metal oxide formed by in situ oxidation assisted by radiation induced photo-acid is described. The method includes depositing a photosensitive material over a metal surface of an electrode. Upon exposure to radiation (for example ultraviolet light), a component, such as a photo-acid generator, of the photosensitive material forms an oxidizing reactant, such as a photo acid, which causes oxidation of the metal at the metal surface. As a result of the oxidation, a layer of metal oxide is formed. The photosensitive material can then be removed, and subsequent elements of the component can be formed in contact with the metal oxide layer. The metal oxide can be a transition metal oxide by oxidation of a transition metal. The metal oxide layer can be applied as a memory element in a programmable resistance memory cell. The metal oxide can be an element of a programmable metallization cell.

  • Publication number: 20130125815
    Abstract: A plasma enhanced atomic layer deposition (PEALD) system used to form thin films on substrates includes a plasma chamber, a processing chamber, two or more ring units and a control piece. The plasma chamber includes an outer and an inner quartz tubular units, whose central axes are aligned with each other. Therefore, plasma is held and concentrated in a cylindrical space formed between the outer and outer quartz tubular units. Due to the first and second through holes, the plasma flow may be more evenly distributed on most of the surface of the substrate to form evenly distributed thin films and nano particles on the substrate. In addition, due to the alignment and misalignment between the first and second through holes, the plasma generated in the plasma chamber may be swiftly allowed or disallowed to enter to the processing chamber to prevent the precursor from forming a CVD.
