Abstract:
An organic copper diffusion barrier layer having low dielectric constant is provided. The organic copper diffusion barrier layer can be applied to a dual damascene structure, which is formed between a copper wiring layer and an organic dielectric layer, to defend copper diffusion from the copper wiring layer into the organic dielectric layer. The organic copper diffusion barrier layer includes a benzocyclo polymer, which it has a benzene ring functional group that can catch copper and prevent copper diffusing into the organic dielectric layer. The problem of thermal diffusion and electro-migration can be avoided.
Abstract:
A method for converting N-bit image data of a digital image into M-bit image data, in which NnullMnullK, K>0, is disclosed. The method is adapted to be used for dithering in an image processing system or a computer graphic system. For example, an N-bit red color value of each pixel of the digital image can be converted into an M-bit red color value by this method with little or no color deviation. According to the method, a difference of the most significant n bits and the least significant n bits of the N-bit image data of a pixel is used as a preliminary criterion for color value conversion, in which n is preferably equal to K. An apparatus for converting N-bit image data of a digital image into M-bit image data, in which NnullMnullK, K>0, is also disclosed. The apparatus includes a subtraction operator for realizing the difference of the most significant n bits and the least significant n bits of the N-bit image data of the pixel.

Abstract:
The present invention discloses a current feedback operational amplifier, whose input ends are connected to a first amplifier which transmits an output to the gate terminals of at least one input pair of current switches, and the source terminal of one transistor of the input pair of current switches is connected to one of the input ends. Therefore, a negative feedback loop will be established by the first amplifier and the input pair of current switches. By means of the negative feedback loop, the input impedance, offset voltage and gain error are all reduced. The input impedance of the present invention is reduced as 1/1nullA times as the original one. Therefore, the aspect ratio of the transistors of the input pair of current switches is reduced.
