摘要:
A pattern on a semiconductor substrate is formed using two separate etching processes. The first etching process removes a portion of an intermediate layer above an active region of the substrate. The second etching process exposes a portion of the active region of the substrate. A semiconductor device formed using the patterning method has a decreased mask error enhancement factor and increased critical dimension uniformity than the prior art.

The present invention provides an apparatus and corresponding method for reducing temporal noise of a target frame and enhancing the motion of the target frame. The apparatus includes a storage device, a temporal noise reducing circuit, and a motion enhancing circuit. The storage device stores a first filtered signal of a previous frame. The previous frame is previous to the target frame. The temporal noise reducing circuit reduces temporal noise of the target frame according to the first filtered signal and an image signal of the target frame. The temporal noise reducing circuit then generates a second filtered signal of the target frame, which is stored in the storage device. The motion enhancing circuit enhances the motion of the target frame according to the first and the second filtered signals, and generates a motion-enhanced signal of the target frame.

The present invention relates to a brightness enhancement film and a backlight module having the brightness enhancement film. The brightness enhancement film includes first micro-reflectors and second micro-reflectors. The cross-section of each of the first and second micro-reflectors is a triangle having two same or different base angles and a wavy crest line. The widths of the first and second micro-reflectors vary along with the valleys and peaks to broaden or to narrow with respect to two sides thereof such that the neighboring lines between the first and second micro-reflectors are wavy. The backlight module is coupled with the brightness enhancement film. This enhances brightness, illuminates evenly, and avoids a moire effect.
