Abstract:
1. A process for improving a material hardness and an elastic modulus of an organosilicate film, the process comprising: depositing the organosilicate film onto at least a portion of a substrate via chemical vapor deposition of an at least one chemical reagent comprising a structure-former precursor to provide the organosilicate film having a first material hardness and a first elastic modulus wherein the depositing step involves one or more processes selected from the group consisting of thermal chemical vapor deposition, plasma enhanced chemical vapor deposition, cryogenic chemical vapor deposition, chemical assisted vapor deposition, hot-filament chemical vapor deposition, photo-initiated chemical vapor deposition, and combinations thereof; and exposing the organosilicate film to an ultraviolet radiation source within a non-oxidizing atmosphere to provide the organosilicate film having a second material hardness and a second elastic modulus wherein the second material hardness and the second elastic modulus are at least 10% higher than the first material hardness and the first elastic modulus.
