    摘要: In a method of manufacturing a thin film transistor, when impurity ions are introduced in a channel region between source and drain regions in a semiconductor layer, an insulator layer is first formed on the semiconductor layer. Then, impurity ions generated on high frequency discharge are introduced through the insulator layer into the semiconductor layer under a specified acceleration voltage. Then, the introduction depth of impurities and the amount of the impurities to be introduced in the channel region can be controlled or the threshold voltage of the thin film transistor can be controlled. This method can be applied to a large substrate.

    摘要: The present invention relates to a thinfilm transistor array designed to drive an active-matrix type liquid-crystal panel to be incorporated in a liquid-crystal display device, and is to offer a thinfilm transistor array solving the conventional problems of disconnections possible between the display electrodes and the drain electrodes and short-circuits possible between the display electrodes and the data wiring. By these, high-quality images can be displayed with a high reliability can be obtained together with an improved fabrication process thereof. In order to accomplish these objectives of the invention, the display electrodes of said thinfilm transistor array are disposed between the gate insulation layer and the inter-insulation layer, and the display electrodes are connected to the drain electrodes by means of a data wiring disposed through contact holes provided through the inter-insulation layer. Furthermore, the possibility of short-circuits can be minimized by insulating and isolating the display electrodes from the data wiring by means of inter-insulation layers, so that the distance between the data wiring and the display electrode can minimized and a remarkable improvement of the displayed image quality can be obtained.
