  • Patent number: 8314423
    Abstract: A thin film transistor array substrate and a manufacturing method thereof are provided. In the manufacturing method, a first patterned conductive layer including a plurality of scan lines and a plurality of gates connected with the scan lines is formed on a substrate. A patterned gate insulating layer having a plurality of openings is then formed on the substrate to cover at least a portion of the first patterned conductive layer, and a plurality of dielectric patterns are formed in the openings. A plurality of semiconductor patterns are formed on the patterned gate insulating layer. A second patterned conductive layer is formed on the semiconductor patterns, the patterned gate insulating layer, and the dielectric patterns. A passivation layer is formed on the semiconductor patterns, the patterned gate insulating layer, and the dielectric patterns. A plurality of pixel electrodes are formed on the passivation layer.

  • Patent number: 7776497
    Abstract: A mask including a transparent substrate, a non-transmitting layer, a first transmitting layer and a second transmitting layer is provided. The transparent substrate has a first region, a second region, and a third region. The non-transmitting layer is disposed in the first region of the transparent substrate. The first transmitting layer is disposed in the second region and the third region of the transparent substrate. The second transmitting layer is disposed on the first transmitting layer in the third region.

  • Patent number: 7704647
    Abstract: A mask and a manufacturing method thereof are provided. A transparent substrate having three regions is provided first. A non-transmitting layer is formed in a first region of the transparent substrate. Then, a first photoresist layer is formed on the transparent substrate, and the first photoresist layer exposes a second region of the transparent substrate. Next, a first transmitting layer is formed on the transparent substrate and the first photoresist layer. Finally, the first photoresist layer is removed. The first transmitting layer on the first photoresist layer is removed at the same time and the first transmitting layer in the second region of the transparent substrate is remained and a third region of the transparent substrate is exposed. A lift-off process is used in the mask manufacturing method of the present invention to form the transmitting layer.

  • Patent number: 7553707
    Abstract: The invention provides a novel technology where a TFT array substrate for a display device is formed with three photomasks. The invention is achieved by using the novel technology in combination with a well-known four-masks process. For the novel technology, during the lithography process where a photosensitive acrylic resin film is used to make contacts, taper patterns required for general through holes are formed simultaneously with a fine pattern formed in a light shielding area that is tapered more approximately to vertical, using a photomask with phase-shift effect. Thus the pixel electrode pattern can be separated without using lithography process in subsequent processes.
