Surface wave plasma treatment apparatus using multi-slot antenna
First Claim
1. A surface wave plasma treatment apparatus, comprising:
- a plasma treatment chamber including a part where said chamber is formed as a dielectric window capable of transmitting a microwave;
a supporting body of a substrate to be treated, said supporting body set in said plasma treatment chamber;
plasma treatment gas introducing means for introducing a plasma treatment gas into said plasma treatment chamber;
exhaust means for evacuating an inside of said plasma treatment chamber; and
microwave introducing means using a multi-slot antenna arranged on an outside of said dielectric window to be opposed to said supporting means of said substrate to be treated, wherein slots arranged radially along which surface waves propagate into peripheral directions and slots arranged annularly along which the surface waves propagate into radial directions are combined as slots.
