  • Publication number: 20110171426
    Abstract: A hard water-repellent structure and a method for fabricating the same are provided. The method adopts an atmospheric pressure plasma deposition (APPD) technique to form a hard coating having a rough surface on a substrate, and form a water-repellent coating on the rough surface. Because the hard water-repellent structure includes the hard coating and the water-repellent coating, hardness, abrasion-resistance, transparency and hydrophobicity of the hard water-repellent structure are improved. The hard water-repellent structure protects the substrate from friction. Moreover, because the disclosure adopts the APPD technique to form the hard water-repellent structure, the cost of production is reduced dramatically. Thus, the disclosure can solve drawbacks of prior art.

  • Publication number: 20070148988
    Abstract: A fabrication method for an alignment film is proposed. A film is deposited on a substrate by an atmosphere plasma in a predetermined direction at a predetermined angle, while moving the substrate and the atmosphere plasma relative to each other. Thereby, a uniform isotropic alignment film with strong anchoring energy is formed and the pre-tilt angle can be designed according to the need. Problems such as static charge and dust generated during a conventional rubbing process are prevented. In addition, since the above fabrication method eliminates the need of vacuum devices that are required in conventional ion beam alignment and plasma beam alignment processes, the fabrication method can be used to fabricate large sized alignment film. Moreover, fabrication cost is lowered through the use of the fabrication method.

  • Patent number: 6341769
    Abstract: A non-contact pick-up device is disclosed. The non-contact pick-up device mainly includes a disk, and a plurality of air nozzles on the disk. Each nozzle has an air channel; and an upper end of the channel is tilt outwards. Therefore, as a disc-shaped article is placed on the disk; air jets out from the nozzles, due to Bernoulli principle, pressure difference is formed on the disc-shaped article. Thus, due to the action of atmosphere pressure, the disc-shaped article will be clamped. The pick-up device may be used in semiconductor manufacturing process for clamping a wafer.

  • Patent number: 6341758
    Abstract: A novel gas control module switch mechanism includes a diaphragm means, a valve body, a piston means and a fastening means. The diaphragm means has a plurality of diaphragms and a seal plate sandwiched between a first and a second diaphragm. The first diaphragm has a center opening to prevent the first diaphragm from making direct sealing contact. Sealing is done through the seal plate. The seal plate is made of a soft material for obtaining improved sealing effect and longer durability. The valve body has a bulged ring around an opening plane and a bulged body ring for enhancing sealing effect when the seal plate making contact with the bulged ring.
