Filed: 1987-11-19
Abstract: PURPOSE:To prevent the generation of a charge-up by a method wherein a scribe-lined region is covered by a metal film with which the scribed line region is electrically conducted, and the excessive charge generating when ions are implanted is streamed away quickly from the rear surface passing through a substrate. CONSTITUTION:An aperture is provided on the insulating film located on the scribe-line region of a semiconductor substrate, and a metal film 3 to be used as a mask for ion-implantation is formed on the above-mentioned aperture. Besides, after the ion-implantation region 4 has been patterned, an ion implanting operation is conducted. The charge caused by the ions implanted into the region other than the ion implantation region flows away to the earth from the whole rear surface of the substrate 1 through the metal film 3. As a result, the generation of charge-up can be prevented.

Abstract: PURPOSE:To eliminate noise component and to display a still picture with high picture quality by reading a voltage of a video signal before one display period stored in each electrode capacitance of each picture element of each line on a display panel in the case of displaying of still picture by a capacitor at the input side of an inverting amplifier, inverting the polarity and applying it to a liquid crystal element through amplification. CONSTITUTION:In the case of still picture display, gate signals X1-Xn outputted from an X driver circuit go sequentially to a high level at an interval of a short period taub for refresh signal at an input terminal 29. Moreover, the refresh signal at the input terminal 29 goes to a high level at each period taub. Just before picture elements 12a, 12b of each line are scanned, the video signal of one preceding line picture element is resident as noise component in capacitors 30, 30'. Thus, the contact 20b of the switch 20 is switched for period taub only based on the high level of the refresh signal. In this case, the discharge path of the capacitors 30, 30' is formed by the switch 20 and the resident signal component in the capacitors 30, 30' is completely discharged.
