Patent ID: 8420170

Claim:
A chemical vapor deposition (CVD) process for depositing borophosphosilicate glass films on a substrate surface, the process comprising: disposing the substrate within a chemical vapor deposition reaction chamber; heating the substrate to a temperature within a range of at least 480° C. to about 700° C.; introducing a gas volume of a SiO 2 precursor into the chamber; admitting a gas volume of ozone into the chamber; admitting a dopant source for phosphorus into the chamber; admitting a dopant source for boron into the chamber; and exposing a reaction volume of the SiO 2 precursor, the ozone, the dopant source for phosphorus, and the dopant source for boron, the reaction volume located above the substrate surface within a chemically reactive distance of the substrate, to a light source without directly exposing the substrate surface to the light source such that borophosphosilicate glass is deposited on the substrate surface.
