Chemistry Of Inorganic Compounds > Silicon Or Compound Thereof > Elemental Silicon Elemental SiliconElemental Silicon patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.04/05/07 - 20070077191 - Method and apparatus for refining silicon using an electron beam A method and apparatus for refining silicon which can remove impurity elements such as phosphorus and antimony as well as impurity elements such as boron and carbon using an electron beam in the same vacuum chamber are provided. Silicon is irradiated and melted with an electron beam in a low ... 01/04/07 - 20070003467 - Low temperature synthesis of semiconductor fibers This invention presents a process to produce bulk quantities of nanowires of a variety of semiconductor materials. Large liquid gallium drops are used as sinks for the gas phase solute, generated in-situ facilitated by microwave plasma. To grow silicon nanowires for example, a silicon substrate covered with gallium droplets is ... 11/03/05 - 20050244324 - Acicular silicon crystal and process for producing the same By uniformly forming an indefinite number of microscopic acicular crystals on a surface of a silicon substrate so as to be perpendicular to the surface of the substrate by plasma CVD method using a catalyst, it is possible to reliably, homogeneously and massively form an ultramicroscopic acicular silicon crystal having ... 06/23/05 - 20050135986 - Dust-free and pore-free, high-purity granulated polysilicon A polycrystalline granulated silicon is made of particles which have a density of greater than 99.9% of the theoretical solid density and therefore have a pore content of less than 0.1% and have a surface roughness Ra of less than 150 nm. ... ### FreshPatents.com Support |
