    摘要: This invention relates to a method for preventing a copy of document, belonging to a technical field of entire copy protection of document. In the prior art, for some important documents, specially the secret ones, the reproduction of this kind of document is usually prohibited by its owner because of the security. But the technique in the prior art can not solve the problem of preventing unauthorized reproduction. The method of the present invention is intended to embed a shading pattern under the original image of anti-copy document by an application program installed in the copy device, and decide whether the document can be copied legally or not. By the method of present invention, it is possible to detect the watermark information of the anti-copy document accurately and quickly, and prevent the reproduction of the anti-copy document thoroughly. Moreover, an additional memory space is no need.

    摘要: A semiconductor device is formed with extended STI regions. Embodiments include implanting oxygen under STI trenches prior to filling the trenches with oxide and subsequently annealing. An embodiment includes forming a recess in a silicon substrate, implanting oxygen into the silicon substrate below the recess, filling the recess with an oxide, and annealing the oxygen implanted silicon. The annealed oxygen implanted silicon extends the STI region, thereby reducing leakage current between N+ diffusions and N-well and between P+ diffusions and P-well, without causing STI fill holes and other defects.

    摘要: A semiconductor is formed on an ETSOI layer, the thin Si layer of an ETSOI substrate, with enhanced channel stress. Embodiments include semiconductor devices having dual stress liners on the back surface of the ETSOI layer. An embodiment includes forming an ETSOI substrate comprising an extra thin layer of Si on a backside substrate with an insulating layer, e.g., a BOX, there between, forming a semiconductor device on the Si surface, removing the backside substrate, as by CMP and the insulting layer, as by wet etching, and forming a stress liner on the backside of the remaining Si layer opposite the semiconductor device. The use of stress liners on the backside of the ETSOI layer enhances channel stress without modifying ETSOI semiconductor process flow.

    摘要: The present invention relates to a method for producing halftone dots in the field of image hard copying, more particularly to a method for frequency-modulation screening using error diffusion based on dual-feedback. In the known frequency-modulation and amplitude-modulation screening technology, it is hard to output a halftone image with high quality using an output equipment with a low resolution (600 dpi) and the satisfactory effect of representing the gradations of the original image in detail and holding the smoothness of the original image can not be achieved. By using the dual-feedback technology based on a basic algorithm of the error distribution, the method in the present invention realizes the organic combination of the conventional frequency-modulation and amplitude-modulation screens and achieves the effect of mixed screening. The method in the present invention can effectively solve the problem of losing gradations of dots in an output equipment with low resolution and can reduce the moire caused by the random distribution characteristic so as to output halftone images with high quality and full gradations.
