20090112013PREPARATION OF SI-SI BOND-BEARING COMPOUNDS - Si—Si bond-bearing compounds are effectively prepared by irradiating with radiation or heating Si—H group-bearing silicon compounds in organic solvents in the presence of iron complex catalysts. The Si—Si bond-bearing compounds are useful as a base material in photoresist compositions, ceramic precursor compositions, and conductive compositions.04-30-2009
20120330045PROCESS FOR CONVERSION OF DISILANES - Highly alkyl-substituted disilanes generally considered as uncleavable, obtained as part of the residue of alkylchlorosilane synthesis, are converted into cleavable disilanes having fewer alkyl groups by reaction with hydrogen halide in the presence of an alumina catalyst. The resulting disilanes can be cleaved into commercially valuable monosilanes by conventional processes.12-27-2012
20140012029METHOD FOR PRODUCING CYCLOHEXASILANE - Provided is a method for efficiently obtaining cyclohexasilane using a cyclic silane dianion salt as a raw material without a by-product such as silane gas by a simple device. The method for producing cyclohexasilane has a feature that a cyclic silane dianion salt represented by the following general formula (i) or general formula (ii) is reacted with an aluminum-based reducing agent or a boron-based reducing agent:01-09-2014

20130184483METHOD OF PRODUCING ALKOXYSILANES AND PRECIPITATED SILICAS FROM BIOGENIC SILICAS - A method of producing alkoxysilanes and precipitated silicas from biogenic silicas is provided. In a first step, biogenically concentrated silica is mixed with a liquid polyol to obtain a mixture, and then the mixture is heated. In a second step, a base is added to obtain a reaction mixture. In a third step, the reaction mixture is filtered to remove the carbon enriched RHA or other undissolved biogenic silica and recover the solution of alkoxysilane and alcoholate. In a fourth step, alkoxysilane is purified by filtering, distilling, precipitating or extracting from the original reaction solution to precipitate various forms of silica. In a final step, residual base present in alkoxysilane is neutralized to eliminate the residual alkali metal base.07-18-2013

20120309999AMMONIUM FLUORIDE CHEMISTRIES - A method of removing at least a portion of a silicon oxide material is disclosed. The silicon oxide is removed by exposing a semiconductor structure comprising a substrate and the silicon oxide to an ammonium fluoride chemical treatment and a subsequent plasma treatment, both of which may be effected in the same vacuum chamber of a processing apparatus. The ammonium fluoride chemical treatment converts the silicon oxide to a solid reaction product in a self-limiting reaction, the solid reaction product then being volatilized by the plasma treatment. The plasma treatment includes a plasma having an ion bombardment energy of less than or equal to approximately 20 eV. An ammonium fluoride chemical treatment including an alkylated ammonia derivative and hydrogen fluoride is also disclosed.12-06-2012
