    • Disclosed is a semiconductor device and method of fabricating the same. The semiconductor device is applicable to various electronic devices such as transistors or memories with transistors. A MOS transistor of the semiconductor device includes a first region and a second region, different in impurity concentration, which are formed in a channel region between source and drain regions. The first region is higher than the second region in impurity concentration. Impurities of the first region are concentrated on a boundary region between an active region and a field isolation film. The first region prevents a punch-through effect in the channel region, while the second region prevents current from decreasing by an increase of impurity during an operation of the transistor. The first region is formed using an additional ion implantation mask, and the second region is formed using an ion implantation mask or formed along with a well.

    • Two electrodes in parallel with each other are formed on one of two substrates, homeotropic alignment films are formed on the substrates and a liquid crystal material having positive dielectric anisotropy is injected between the substrates. When the voltage is applied to the two electrodes, a parabolic electric field between the electrodes drives the liquid crystal molecules. Since the electric field generated is symmetrical with respect to the boundary-plane equal distance from each of the two electrodes, the liquid crystal molecules are symmetrically aligned with respect to the boundary-plane. The electric field does not exert influences the liquid crystal molecules on the boundary-plane since the electric field on the boundary-plane is parallel with the substrates and perpendicular to the two electrodes; and thus, it is perpendicular to the liquid crystal molecules. Here, the polarization of the light is changed while passing through the liquid crystal layer and as a result, only a part of the light passes through the polarizing plate. The transmittance of the light can be varied by controlling the magnitude of voltage applied to the two electrodes.
    • 在两个基板之一上形成彼此平行的两个电极,在基板上形成垂直取向膜,并且在基板之间注入具有正介电各向异性的液晶材料。 当电压施加到两个电极时,电极之间的抛物线电场驱动液晶分子。 由于产生的电场相对于与两个电极中的每一个相等的边界面等距离是对称的,所以液晶分子相对于边界平面对称地排列。 由于边界平面上的电场平行于基板并垂直于两个电极,所以电场不会对边界平面上的液晶分子产生影响; 因此它垂直于液晶分子。 这里,光的偏振通过液晶层而变化,结果只有一部分光通过偏振片。 可以通过控制施加到两个电极的电压的大小来改变光的透射率。

    • In a optically compensated bend (OCB) liquid crystal display, an impulsive voltage is applied to a pixel between applications of normal data voltages for displaying an image, and the impulsive voltage and the normal data voltage are controlled to prevent breaking of the bending alignment of the (OCB) liquid crystals. Accordingly, luminance of the liquid crystal display can be improved.When the normal data voltage of 0V is applied, the impulsive voltage at which the bending alignment of OCB liquid crystal is broken is set to the impulsive voltage at (for, corresponding to) the highest gray. There occurs a broken region (0-VB) where the bending alignment of the OCB liquid crystal is broken at a predetermined range that is higher than 0V. A voltage that is higher than the highest voltage (VB) of the broken region is set to a white voltage. Accordingly, luminance of the OCB liquid crystal display can be enhanced.
