摘要： A method of forming a contact opening in a semiconductor substrate is presented. A plurality of trench gates each having a projecting portion are formed in a semiconductor substrate, and a stop layer is deposited over the semiconductor substrate extending over the projecting portions, wherein each portion of the stop layer along each of the sidewalls of the projecting portions is covered by a spacer. By removing the portions of the stop layer not covered by the spacers by utilizing a relatively higher etching selectivity of the stop layer to the spacers, the openings between adjacent projecting portions with an L-type shape on each sidewall can be formed, and a lithography process can be performed to form self-aligned contact openings thereafter.

摘要： A dual-frequency bistable liquid crystal display and the liquid crystal mixture thereof includes liquid crystal cell filled with a liquid crystal mixture which contains dual-frequency liquid crystal, chiral compound, and nematic liquid crystal mixture. The liquid crystal mixture has the characteristics of both the dual-frequency liquid crystal and cholesteric liquid crystal. The dual-frequency bistable liquid crystal display is driven in a frequency modulation mode and can be switched between two optical states by taking advantage of the dielectric anisotropy of the liquid crystal, which results in a short switching time and sharp contrast between two optical states. Furthermore, the maintaining of the two optical states requires no voltage, which does not require the use of a high voltage to destabilize the helical structure of the cholesteric liquid crystal, and does not have to go through a metastable stage. Hence, power consumption and switching time are reduced.

摘要： The present invention discloses a REPEATED-SCAN driving method, which applies to a field sequential color liquid crystal display, wherein each sequential-color cycle of the multiplex-scan signal has at least two stages of scans to increase the luminous fluxes of all colors of backlights and bring closer the total amounts of fluxes, whereby is achieved higher color saturation and better flux uniformity between the rows. Further, the method of the present invention controls the backlights to form dark stages between the intervals respectively of two different colors of the backlights and controls the dark stage to coincide with a color-mixing interval, which is caused by response delay of liquid crystal, to prevent from color distortion caused by color mixing. Therefore, the present invention can generate the pure colors and the designed derived colors accurately.
