  • Patent number: 6797961
    Abstract: An X-ray sensing array substrate that includes a storage capacitor having first and second capacitor electrodes and a pixel electrode over the storage capacitor. One of the capacitor electrodes contacts a drain electrode of a thin film transistor through a first contact hole in an insulating layer. The pixel electrode contacts that capacitor electrode through a second contact hole through a second insulting layer. Therefore, the drain electrode is connected to the storage capacitor through only one contact, while the pixel electrode contacts the storage capacitor through only one contact. This reduces the drain electrode to capacitor resistance, reduces the voltage drop, and increases the sensitivity of the array.

  • Publication number: 20040183023
    Abstract: An array substrate for use in an X-ray sensing device includes a silicon insulator on a thin film transistor. The silicon insulator is silicon nitride or silicon oxide that has a strong adhesive strength to the active layer of the thin film transistor. Thereafter, an organic material, as a planarizing layer, is formed on the silicon insulator, so that the leakage current, which has a bad influence on the operation of the thin film transistor, can be prevented.
