  • Patent number: 9404181
    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 an annular 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.

  • Patent number: 8995060
    Abstract: A head-up display device includes an image module, a substrate, and an optical film. The image module has an emitting source, wherein the emitting source transmits at least one image. The substrate is disposed corresponding to the image module. The optical film is disposed on the substrate and includes at least one transmission layer, wherein each transmission layer has a plurality of transmitting column structures obliquely arranged side by side, and a longitudinal direction of the transmitting column structure has a tilt angle with respect to a normal of the substrate. The at least one image is transmitted to the optical film, and the obliquely disposed transmitting column structures cause the at least one image to scatter on the optical film.

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.

  • Patent number: 8236433
    Abstract: An antireflection structure is provided. The antireflection structure includes a substrate layer having a substrate refractive index; a first inorganic layer disposed on the substrate layer and having a first refractive index different from the substrate refractive index, where a thickness of the first inorganic layer is in a range of 1 to 40 nm; and a second inorganic layer disposed on the first inorganic layer and having a second refractive index different from the first refractive index.

  • Publication number: 20110250414
    Abstract: A novel TCO coating and its manufacturing method are disclosed. The TCO coating of the present invention consists of titanium oxide, silicon oxide and metal. The TCO coating is manufactured according to electromagnetic field simulation software basing on the Maxwell Equations. Because the manufacturing method (including steam plating and sputter plating) of the present invention may be carried out under the room temperature, base boards that are made of polymer and that can not withstand high temperatures may be used and hence base boards may have wider applications. Also, less time is needed in the production, production cost is lowered and mass-production may be achieved.

  • Publication number: 20090098307
    Abstract: A manufacturing method for a far-infrared irradiating substrate is provided. The manufacturing method comprises steps of providing a substrate, providing a far-infrared irradiating material and evaporating the far-infrared irradiating material to form a thin film onto the substrate. The far-infrared irradiating substrate provided by the present invention not only has a high emission coefficient of far-infrared ray, but also do not cause a potential exposure of an ionizing radiation.
