Title:
HIGH FREQUENCY PLASMA PROCESSING SYSTEM
Document Type and Number:
Japanese Patent JP3279744
Kind Code:
B2
Abstract:

PURPOSE: To provide a high frequency plasma processing system in which generation of reaction products is suppressed in a discharge tube and adhesion thereof to the wall surface or falling there onto a substrate is prevented.
CONSTITUTION: The high frequency plasma processing system comprises a vacuum vessel 1 equipped with a discharge tube 4, a mechanism 8 for evacuating the vessel 1, a mechanism 9 for introducing a reaction gas into the vessel, a mechanism 10 for supplying high frequency power into the discharge tube to generate plasma of the reaction gas, and a substrate holding mechanism 2 disposed oppositely to the discharge tube in the vessel, wherein the discharge tube 4 is provided with an electrode 5 which is applied with a bias voltage at a part opposing the substrate holding mechanism. The electrode is coated with a film as required. A temperature regulator 12 for setting the temperature on the surface of the electrode at an arbitrary level is also provided.
