Abstract
A circuit array substrate is provided with thin-film transistorsandand PIN diodeformed on insulation substrate. Active layerand photo-electric sensor portionare made of poly-silicon films. Impurities are doped into active layerand photo-electric sensor portionin the same process chamber, if necessary, to make their impurity concentrations different from each other. Thin-film transistorsandwith prescribed characteristics and PIN diodewith improved photosensitivity can be simultaneously, easily manufactured on insulation substratewith a lesser number of processes.
