Abstract
A chemical vapor deposition system that includes a housing configured to form a processing chamber, a substrate holder configured to hold a substrate within the processing chamber, a gas distribution system configured to introduce gases into the processing chamber, a plasma generation system configured to form a plasma within the processing chamber, a processor operatively coupled to control the gas distribution system and the plasma generation system, and a computer-readable memory coupled to the processor that stores a computer-readable program which directs the operation of the chemical vapor deposition system. In one embodiment the computer-readable program comprises instructions that control the gas distribution system to flow a process gas comprising silicon, oxygen and a halogen family member into the chamber to deposit a halogen-doped silicon oxide film on a substrate positioned on the substrate holder and instructions that control the gas distribution system and plasma generation system to densify the halogen-doped silicon oxide film by bombarding the film with ionic species from a plasma of an argon-containing gas source. In another embodiment, the computer-readable program comprises instructions that control the gas distribution system to flow a process gas comprising silicon, oxygen and a halogen family member into the chamber to deposit a halogen-doped silicon oxide film on said substrate and instructions that control the gas distribution system and plasma generation system to form a plasma from a hydrogen containing source gas to bombard the halogen-doped silicon oxide film with hydrogen ions to remove loosely bound halogen atoms from the film.
