Each driving module includes a voltage boost stage and n driving stages. The voltage boost stage is used for receiving a first master signal of the m master signals and converting the first master signal into a first high voltage signal, wherein a high logic level of the first master signal is increased to a highest voltage by the voltage boost stage. The n driving stages receives the n slave signals, respectively, and receives the first high voltage signal. In response to the highest voltage of the first high voltage signal, the n driving stages sequentially generates n gate driving signals according to the n slave signals.

  • Chemical-Vapor-Deposition Repair Apparatus
    Publication number: 20140053775
    Abstract: Embodiments of the present invention provide a CVD repair apparatus, in which an auxiliary gas is ejected from a gas-storage module, impinging upon a substrate, and bounced back to a pressure-sensitive sensor provided on a lower surface of a gas-ejection device, so that the gas pressure is detected, and based on the detected gas pressure, the distance between the substrate and the gas-ejection device is determined; when the distance between the substrate and the gas-ejection device is less than a preset lower-limit value, by increasing the auxiliary-gas amount ejected from the gas-storage module to lift up the gas-ejection device, or by preventing the gas-ejection device from moving parallel to the substrate, the substrate is avoided an inadvertent scratch during the movement of the gas-ejection device.
