  • Circuit array substrate and method of manufacturing the same
    Publication number: 20050017318
    Abstract: A circuit array substrate is provided with thin-film transistors 4 and 5 and PIN diode 6 formed on insulation substrate 3. Active layer 11 and photo-electric sensor portion 21 are made of poly-silicon films. Impurities are doped into active layer 11 and photo-electric sensor portion 21 in the same process chamber, if necessary, to make their impurity concentrations different from each other. Thin-film transistors 4 and 5 with prescribed characteristics and PIN diode 6 with improved photosensitivity can be simultaneously, easily manufactured on insulation substrate 3 with a lesser number of processes.
