The high purity acetylene product is useful as a source material for depositing carbon and carbon-containing films in semiconductor applications. | 12-23-2010 |
20130048143 | CYLINDER PREPARATION FOR HIGH PURITY ACETYLENE - This invention relates in part to a method for preparing a pressure vessel for receiving high purity acetylene at elevated pressure. The method involves providing a porous filler-containing pressure vessel, deep cleaning the porous filler-containing pressure vessel, purifying a solvent, and charging the purified solvent into the deep cleaned, porous filler-containing pressure vessel. The pressure vessel is then charged with high purity acetylene for storage, transport and/or delivery of the high purity acetylene. The high purity acetylene may be useful as a source material for depositing carbon and carbon-containing films in semiconductor applications. | 02-28-2013 |
