  • Publication number: 20060019441
    Abstract: A process for fabricating non-volatile memory by tilt-angle ion implantation comprises essentially the steps of implanting sideling within a nitride dielectric layer heterogeneous elements such as, for example, Ge, Si, N2, O2, and the like, for forming traps capable of capturing more electrons within the nitride dielectric layer such that electrons can be prevented from binding together as the operation time increased; etching off both ends of the original upper and underlying oxide layers to reduce the structural destruction caused by the implantation of heterogeneous elements; and finally, depositing an oxide gate interstitial wall to eradicate electron loss and hence promote the reliability of the device.

  • Publication number: 20050233495
    Abstract: A technique to grow high quality and large area ZnSe layer on Si substrate is provided, comprising growing GexSi1-x/Ge epitaxial layers on Si substrate by using ultra-high vacuum chemical vapor deposition (UHVCVD), and finally growing a ZnSe film on top Ge buffer layers. Two concepts are applied in the process of this invention, the first one is to block the dislocations generated from GexSi1-x epitaxial layers and to terminate the propagated upward dislocations by using strained interfaces, accordingly the dislocation density of ZnSe layer is greatly reduced and the surface roughness is improved; the second concept is to solve the problems of anti-phase domain due to growth of polar materials on non-polar material using off-cut angle Si substrate, and that is free from diffusion problems between different atoms while generally growing ZnSe layers on Si substrate.

  • Publication number: 20050156228
    Abstract: The manufacturing method of a nonvolatile memory and its structure is achieved by building a gate dielectric layer on a base. The gate dielectric layer contains at least two layers of different material layers. At least one hetero element is planted on the top of the gate dielectric layer so as to increase the electronic trap density. Then rebuild a new top material after removing the upmost layer of material. Finally, build a gate electrode layer on the gate dielectric layer and form source/drain electrodes at the bases of both sides of the gate dielectric layer. In this invention, with the planting of the hetero element, it will form traps in the gate dielectric layer that can catch electrons more easily. Thus, the electrons won't combine together with the increase of operation time. The storage time can be effectively extended and the problem of the combination of bites can be solved.

  • Patent number: 6004560
    Abstract: A nasal spray (drop) for treating fever/cold, and its preparation. The nasal spray (drop) is made by: obtaining a liquid by boiling Bupleurum Scorzonerifolium Willd, Radix Lastidis Lndigotica and Folium Lastidis for a long time in water, and then mixing the liquid thus obtained with Vitamin C. The nasal spray (drop) can be directly applied to the nasal cavity, and absorbed by the nasal mucosa to clear heat and sore, to release influenza symptoms such as head ache, stuff nose, coughing, sore throat, sneezing, nose-dropping and whole-body pain, and to treat fever due to infection of upper respiratory tract.

  • Patent number: 4654064
    Abstract: A process of separating a multi-component liquid mixture containing n major components by forming crystals of m components, denoted as m crystallizing components, in a crystallization zone, denoted as a first processing zone, having k crystallization sub-zones, the value of m being equal to or greater than 2 and equal to or less than n, the value of k being equal to or greater than 1 and equal to or less than m, comprising a first step of crystallizing the m components in the k crystallization sub-zones to form a first condensed mass and a second step of vaporizing a mass of the volatile component(s) from the liquid mixture to form a first vapor in each sub-zone under a first pressure that is lower than the eutectic pressure defined as the equilibrium pressure at which the m solid phases and the liquid mixture co-exist with a vapor phase containing the volatile component(s), wherein the said first step and the second step are conducted simultaneously so that at least a major fraction of the heat released in S
