| Zusammenfassung: | An apparatus for large area plasma processing according to the invention comprises at least one plane antenna (A) having a plurality of interconnected elementary resonant meshes (M1, M2, M3), each mesh (M1, M2, M3) comprising at least two conductive legs (1, 2) and at least two capacitors (5, 6). A radiofrequency generator excites said antenna (A) to at least one of its resonant frequencies. A process chamber is in proximity of said antenna (A). Said antenna (A) produces an electromagnetic field pattern with a very well defined spatial structure, which allows a great control on the excitation of the plasma. |
