  • Patent number: 7834837
    Abstract: An exemplary active matrix LCD (200) includes an LCD panel, a gate driver (211), a data driver (212), and a voltage compensating circuit (240). The LCD panel includes a plurality of gate lines (221) and a plurality of data lines (222) crossing the data lines to define a plurality of pixel units (230). Each pixel unit includes a liquid crystal capacitor (227) and a TFT (223). The liquid crystal capacitor includes a pixel electrode (224) and a common electrode (225). The voltage compensating circuit is configured for detecting a first voltage of a source electrode of one of the TFTs when the TFT turns on, detecting a second voltage of a drain electrode of the TFT when the TFT turns off, and then outputting a compensating voltage according to the first voltage and the second voltage for compensating a kick-back voltage of the TFT.

  • Patent number: 7514184
    Abstract: A static resistant reticle comprises a substrate and a patterning layer and is covered by an antistatic conductive film of quaternary amine (R4N)+Cl?. A pellicle structure comprising an optically transparent membrane tightly stretched on a frame is also coated by an antistatic electro conductive film of a similar material. The reticle with the pellicle form a shielded structure isolating the reticle from ESD.

  • Publication number: 20070248895
    Abstract: A method for reducing defect levels in a photomask by employing a cleaning process which does not degrade the photomask after multiple cycles of cleaning. The method is suitable for patterned metal stencil photomasks and phase shift photomasks. The method employs an alkaline aqueous cleaning solution for a particular time in a particular temperature range. The method results in improved photomask yield after multiple cleaning cycles.

  • Patent number: 6948619
    Abstract: A pod for transporting reticles is made with a reticle support that has a ?-shape and is provided with pins, whose arrangement matches the location of chrome-free areas on a reticle base. Due to that, the pins, when supporting the reticle, come into contact with the reticle in chrome-free areas thereof. Thus, scratching the metallic areas and releasing metallic particles is prevented from occurring.

  • Patent number: 6869733
    Abstract: The present invention is a method of protecting reticles from electrostatic damage during their use in manufacturing lines and while patterning photoresist films on device substrates. An anti-static layer comprised of an ammonium salt is formed on both sides of a pellicle which is then attached to a metal frame that has been coated with an anti-static layer of the ammonium salt. The frame with attached pellicle is connected to a reticle by an adhesive. Any electrostatic charges that form on the surface of the anti-static layers or on the reticle are conducted into the metal frame where they are dissipated. The ammonium salt is preferably (RN4+) Cl— in which (RN4+) has the structure: where Y is an alkyl group or C6H4, m=1 to 10000, and X? is Cl?.
