Abstract:
A processing system for a substrate, said system comprising:a body defining a vacuum chamber;a holder disposed within said vacuum chamber, said holder adapted to support said substrate;a supply of gases, said supply including a silicon source, an oxygen source and a fluorine source;a gas distribution system in fluid communication with both said vacuum chamber and said supply of gases and adapted to introduce gases of said supply into said vacuum chamber, with gases present in said vacuum chamber defining a process gas;a heater in thermal communication with said substrate holder;a vacuum system in fluid communication with said vacuum chamber;a processor in data communication with said gas distribution system, said heater and said vacuum system;a memory in data communication with said processor; anda computer readable program disposed within said memory which causes said processor to regulate operation of said gas distribution system, said heater and said vacuum system, said computer readable program including a first set of computer instructions adapted to control said vacuum system to set and maintain said vacuum chamber at a selected pressure, a second set of computer instructions adapted to control said gas distribution system to introduce said silicon source, said oxygen source and said fluorine source into said vacuum chamber to deposit a fluorosilicate glass layer over said substrate, and a third set of computer instructions controls said heater to heat said holder to a selected temperature and maintain said substrate at approximately 300 to 550 degrees C for approximately 30 to 120 seconds, after deposition of said fluorosilicate glass layer.
