Abstract: A method which allows conventional photolithography technique to be used for fabricating deep submicron MOS transistors with commercially satisfactory yield rate is disclosed. The method involves the steps of :(1) forming a first dielectric layer having a trench region on a substrate; (2) forming a doped silicate-glass oxide layer covering the first dielectric layer; (3) forming a second dielectric layer covering the doped silicate-glass oxide layer; (4) using an anisotropic etching technique to etch the second dielectric layer and form a pair of dielectric sidewall spacers; (5) removing the portion of the silicate-glass oxide layer disposed between the pair of dielectric sidewall spacer; (6) implementing a gate oxidation procedure which caused a gate oxide layer to be grown on top of the channel region, and, at the same time, the dopant in the silicate-glass oxide layer is out-diffused into the substrate to form an LDD region; (7) depositing a polysilicon layer in the gate region defined between the pair of dielectric sidewall spacers to form a gate electrode. In the step(4), the dielectric sidewall spacers are formed such that the gate electrode will have a width which generally increases with distance from the substrate.

Title: Liquid crystal display panel and the control method thereof
Inventor: LAY CHUNG-WEN
IPC: G09G3/36
Filed: 2000-08-08
Granted: 2002-03-11
Abstract: A liquid crystal display panel and the control method thereof are disclosed, wherein the video signal used is dot inversion or column inversion type. The invention is characterized in disposing a recycle transistor between the adjacent display units in the same scanning line, connecting the gate to the previous scanning electrode, and connecting the source and drain to the display electrode between these two display units. When the previous scanning electrode is scanned, the recycle transistor will be turned on and the coupled charges in the display electrode is redistributed. Since the polarities of the original video signal are different, the display electrode voltage will be very close to the common electrode voltage after redistribution, so that, when this scanning line is scanned, it only needs to rise up to the positive polarity or fall down to the negative polarity from the common electrode voltage.
