Zusammenfassung: | A process to stabilize nitrogen-containing or oxygen-containing organosilane from acid catalyzed attack and retard the resulting decomposition is disclosed. Such organosilanes, and the nitrogen-containing organosilane in particular, with a least one Si-H or N-H group are susceptible to this type of product decomposition. Treatment with a weakly basic ion exchange media retards this decomposition by scavenging the anions or acids that are attacking the Si-H group. Dilute exposures to these anions can initiate significant decomposition and effect product stability and long-term shelf-life for semiconductor processing for the use of silicon oxide, silicon oxynitride and silicon nitride films. |
