Abstract:
A method of forming a metal semiconductor alloy that includes forming an intermixed metal semiconductor region to a first depth of a semiconductor substrate without thermal diffusion. The intermixed metal semiconductor region is annealed to form a textured metal semiconductor alloy. A second metal layer is formed on the textured metal semiconductor alloy. The second metal layer on the textured metal semiconductor alloy is then annealed to form a metal semiconductor alloy contact, in which metal elements from the second metal layer are diffused through the textured metal semiconductor alloy to provide a templated metal semiconductor alloy. The templated metal semiconductor alloy includes a grain size that is greater than 2× for the metal semiconductor alloy, which has a thickness ranging from 15 nm to 50 nm.

Abstract:
Disclosed is a method for scanning and processing an image using the error diffusion screening technology, comprising: (1) scanning each pixel Mi of an nth line in an original image one by one and then storing a scanning result of the pixel Mi to an ith storage location; and (2) processing the stored result of the pixel Mi by using error diffusion and scanning pixels of an n+1th line in the original image until all pixels of the nth line have been processed and all pixels in the n+1th line have been scanned and stored, wherein once processing for the pixel Mi is completed, a scanning result of a pixel of the n+1th line is stored to the ith storage location previously occupied by the pixel Mi. Based on the method, the capacity for storing is only required to be able to store the data of one line in an image in the scanning direction, which saves the storage for bidirectional scanning. The method can optimize the hardware used to implement error diffusion and improve the operating efficiency. Also disclosed is a system for achieving the method.

Silicidation techniques with improved rare earth silicide morphology for fabrication of semiconductor device contacts. For example, a method for forming silicide includes implanting a silicon layer with an amorphizing species to fond an amorphous silicon region in the silicon layer and depositing a rare earth metal film on the silicon layer in contact with the amorphous silicon region. A silicide process is then performed to combine the rare earth metal film and the amorphous silicon region to form a silicide film on the silicon layer.

A method of fabricating a Schottky field effect transistor is provided that includes providing a substrate having at least a first semiconductor layer overlying a dielectric layer, wherein the first semiconductor layer has a thickness of less than 10.0 nm. A gate structure is formed directly on the first semiconductor layer. A raised semiconductor material is selectively formed on the first semiconductor layer adjacent to the gate structure. The raised semiconductor material is converted into Schottky source and drain regions composed of a metal semiconductor alloy. A non-reacted semiconductor material is present between the Schottky source and drain regions and the dielectric layer.
Abstract:
Interior microchannels within microchannel apparatus are uniformly coated. Remarkably, these uniform coatings are formed from materials that are applied to the interior microchannels after an apparatus has been assembled or manufactured. Coatings can be made uniform along the length of a microchannel, in the corner of a microchannel, and/or throughout numerous microchannels in an array of microchannels. Techniques for tailoring the application of washcoats onto microchannels is also described.

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.
