Filed: 1987-07-28
Abstract: PURPOSE:To double a liquid crystal driving speed by setting the common period of driving signals prepared with respect to respective column-directional electrodes and respective row-directional electrodes to twice as long as a unit time and generating those kinds of driving signals so that their DC components are zero at least in said double period. CONSTITUTION:A liquid crystal display device 1 is provided with (n) scanning electrodes L and (n) signal electrodes S in mutual crossing directions and picture elements A are arranged at their intersections in a matrix. A scanning electrode driving circuit 2 and a signal electrode driving circuit 3 are connected to the electrodes L and S and voltages of optional levels are applied selectively. In this constitution, each selection period is set to twice as long as the unit time length, a 1st prescribed voltage applied in the beginning of the double selection period, and a 2nd prescribed voltage is applied at the following end of the period. Namely, the voltage is lowered to zero at the end to cancel DC components applied to the respective picture elements in the selection period. Thus, the driving speed is increased without causing any deterioration of the picture elements.

Title: Manufacture of semiconductor device
Inventor: YUYA NAOKI
IPC: H01L21/205
Filed: 1984-09-07
Abstract: PURPOSE:To easily make mask alignment by making the first exposed insulation film as a reference, by a method wherein the width of the positioning pattern part is made larger than that for element isolation at the time of forming the first insulation film. CONSTITUTION:An insulation film is formed on the main surface of an Si substrate 1. At the time of forming apertures 3 by photoetching or the like, the width D2 of the insulation film 2A of the positioning pattern part is made larger than the width D1 of the insulation film 2 for element isolation. Thereby, even when the insulation film 2 is completely covered with a semiconductor layer 4 at the time of forming this layer 4, the insulation film 2A of the positioning pattern part is not covered but exposed in the front. Therefore, mask alignment can be easily made.
