Abstract:
1. A method for depositing a conformal film on a substrate in a plasma processing chamber of a plasma processing system, said substrate being disposed on a chuck, said chuck being coupled to a cooling apparatus, said method comprising: flowing a first gas mixture into said plasma processing chamber at a first pressure, wherein said first gas mixture has a condensation temperature; cooling said chuck below said condensation temperature using said cooling apparatus after said flowing said first gas mixture into said plasma processing chamber at said first pressure, thereby allowing at least some of said first gas mixture to condense on a surface of said substrate; venting said first gas mixture from said processing chamber; flowing a second gas mixture into said plasma processing chamber, said second gas mixture being different in composition from said first gas mixture; and striking a plasma to form said conformal film.
