Provided are functionalized silicon compounds and methods for their synthesis and use. The functionalized silicon compounds include at least one activated silicon group and at least one derivatizable functional group. Exemplary derivatizable functional groups include hydroxyl, amino, carboxyl and thiol, as well as modified forms thereof, such as activated or protected forms. The functionalized silicon compounds may be covalently attached to surfaces to form functionalized surfaces which may be used in a wide range of different applications. In one embodiment, the silicon compounds are attached to the surface of a substrate comprising silica, such as a glass substrate, to provide a functionalized surface on the substrate, to which molecules, including polypeptides and nucleic acids, may be attached. In one embodiment, after covalent attachment of a functionalized silicon compound to the surface of a solid silica substrate to form a functionalized coating on the substrate, an array of nucleic acids may be covalently attached to the substrate. Thus, the method permits the formation of high density arrays of nucleic acids immobilized on a substrate, which may be used, for example, in conducting high volume nucleic acid hybridization assays.

A semiconductor wafer includes an oxide film above a silicon layer, and a porous silicon layer which is located above the oxide film and serves as a gettering layer. Gettering of impurities from a silicon layer is not interrupted by the oxide film since the porous silicon layer is placed above the oxide film. The semiconductor wafer having the structure above can be produced by a bonding method. Bonding strength relative to the oxide film is ensured by placing a growth silicon layer between the oxide film and the porous silicon layer, compared with the case in which the oxide film and the porous silicon layer are directly bonded.

A semiconductor wafer provided with a thermosetting porous insulating film, wherein the insulating film is made porous, cured and polymerized on the wafer. The film is characterized by a very low dielectric constant based on its constituency and porosity, the latter property of which is caused by the inclusion of liquid or supercritical carbon dioxide in the polymeric reaction mixture.

In the present invention, a masterbatch is produced by melt-mixing a metal compound (B) with a reactive thermoplastic resin (C). The oxidizable polyamide (A) is produced by polycondensing a diamine component containing m-xylylenediamine in an amount of 70 mol % or higher with a dicarboxylic acid component containing adipic acid in an amount of 50 mol % or higher. The metal compound (B) contains at least one metal selected from the group consisting of transition metals in group VIII of the periodic table, manganese, copper and zinc. The reactive thermoplastic resin (C) has an internal bond and/or a reactive functional group which are reactive with an amide bond and/or a reactive functional group of the oxidizable polyamide (A). The masterbatch exhibits a stable moldability. The masterbatch is melt-mixed with an oxidizable polyamide (A) and formed into a molded article which exhibits an excellent oxygen-absorbing ability irrespective of the preservation conditions of the masterbatch.
摘要:
A method of forming a substantially relaxed, high-quality SiGe-on-insulator substrate material using SIMOX and Ge interdiffusion is provided. The method includes first implanting ions into a Si-containing substrate to form an implant rich region in the Si-containing substrate. The implant rich region has a sufficient ion concentration such that during a subsequent anneal at high temperatures a barrier layer that is resistant to Ge diffusion is formed. Next, a Ge-containing layer is formed on a surface of the Si-containing substrate, and thereafter a heating step is performed at a temperature which permits formation of the barrier layer and interdiffusion of Ge thereby forming a substantially relaxed, single crystal SiGe layer atop the barrier layer.
