  • Patent number: 7727553
    Abstract: The present invention provides oral preparations with good disintegration containing a slightly water-soluble active ingredient, which comprise a mixture of a solid formed product (e.g. a granule) and a second disintegrant wherein said solid formed product comprises a slightly water-soluble active ingredient, a first disintegrant and a water-soluble excipient which is formed by using a water-soluble polymer binder; or comprises a solid formed product prepared from a slightly water-soluble active ingredient, a disintegrant and a sugar alcohol by using a water-soluble polymer binder. When orally administered, these oral preparations exhibit excellent dissolution characteristics of the active ingredient in the digestive tract, and further, these preparations can show equivalent dissolution profile even at different amounts of the active ingredient, and thus enable the selection of the most suitable medicament for each patient, which makes these preparations highly useful in the clinical field.

  • Patent number: 6881650
    Abstract: A method for forming SOI substrates including a SOI layer containing germanium and a strained silicon layer disposed on the SOI layer, comprises forming a relaxed silicon-germanium layer on a first silicon substrate using an epitaxial growth method, and forming a porous silicon-germanium layer thereon. A silicon-germanium epitaxial layer is formed on the porous silicon-germanium layer, an oxide layer is formed on a second silicon substrate, the second silicon substrate is bonded where the oxide layer is formed to the first silicon substrate where the silicon-germanium epitaxial layer is formed. Layers are removed to expose the silicon-germanium epitaxial layer and a strained silicon epitaxial layer is formed thereon. The porous silicon-germanium layer prevents lattice defects of the relaxed silicon-germanium layer from transferring to the silicon-germanium epitaxial layer. Therefore, it is possible to form the silicon-germanium layer and the strained silicon layer of the SOI layer without defects.

  • Patent number: 5624498
    Abstract: A gas supply apparatus, for use in a semiconductor device manufacturing process, provides a showerhead for evenly supplying various kinds of gases to a reaction chamber. The gas supplying apparatus for use in the formation of a thin film of a semiconductor device includes a first porous plate having a plurality of first holes formed throughout its surface, and a central bore formed at its center; and a second porous plate having first projections which are regularly formed throughout its central portion, and second projections which contain depressions continuously formed around the first projections. The gas supplying apparatus evenly distributes gas into the reaction chamber, thereby improving the uniformity of the film thickness to be grown on a substrate.
