| titleOfInvention | Process for removing carbon material from substrates |
| abstract | A method of removing carbon materials, preferably amorphous carbon, from a substrate includes dispensing a liquid sulfuric acid composition including sulfuric acid and/or its desiccating species and precursors and having a water/sulfuric acid molar ratio of no greater than 5:1 onto an material coated substrate in an amount effective to substantially uniformly coat the carbon material coated substrate. The liquid sulfuric acid composition is exposed to water vapor in an amount effective to increase the temperature of the liquid sulfuric acid composition above the temperature of the liquid sulfuric acid composition prior to exposure to the water vapor. In preferred embodiments, amorphous carbon is selectively removed as compared to a silicon oxide (e.g., silicon dioxide) and/or silicon nitride. |
