Title: Method for driving liquid crystal display element
Inventor: KUWATA TAKESHI
IPC: G02F1/133
Filed: 1992-07-08
Abstract: PURPOSE:To suppress variation in an optical state small by dispersing plural selection pulses in one frame. CONSTITUTION:Row electrodes are denoted by R1-R4 and a time interval T is a time interval for selecting a subgroup once when N row electrodes are all divided into subgroups at every L electrodes. When every L row electrodes of the N row electrodes are selected in a batch to make a binary display, the number of selection pulses which should be applied to the respective row electrodes to make one display is at least 2K.(N/L) and almost equal to 2N in a conventional voltage averaging method. The number of selective pulses which are applied while one display is made is 2L when, for example, L=2p (p: integer) and they are dispersed and applied to shorten the time when no selective voltage is applied to the row electrodes to 1/L as long as before. Namely, the number of the selective pulses can be increased substantially without varying the width of the selective pulses. Therefore, the method is effective in driving at a <=50msec mean response velocity at the time of dynamic driving.

IPC: H01L21/8242
Filed: 1991-08-15
Abstract: PURPOSE: To provide an improved method for growing a thin gate oxide having high quality on single crystal silicon.  
     CONSTITUTION: A silicon dioxide film is formed by plasma enhanced thermal oxidation in this method. This thermal oxidation is executed at a temp. lower than about 440°C by using a mixture composed of ozone and oxygen of a volumetric ratio of about 1-10 to 1 generated outside a process chamber 10. This method is used in order to form sidewall oxide spacers on polysilicon gates for field effect transistors. A fairly high oxidation rate is obtd. at the temp. sufficiently lower than the temp. of the prior art. As a result, the diffusion of dopants from the polysilicon is lessened. The stress of the generated films is small and the polysilicon gates are well coated to a co-shape. The films having uniform thicknesses are formed by controlling a temp., high-frequency electric power, exposure time and oxygen/ozone ratio.
