First Claim
1. A wide ion beam source comprising:
- a plurality of RF windows arranged in a predetermined relationship;
a single plasma chamber disposed on a first side of the plurality of RF windows;
a plurality of RF antennas, each RF antenna of the plurality of RF antennas disposed on a second side of a respective RF window of the plurality of RF windows, the second side being opposite the first side; and
a plurality of RF sources, each RF source coupled to a respective RF antenna of the plurality of RF antennas, wherein a difference in frequency of a first RF signal produced by a first RF source coupled to a first RF antenna from that of a second RF signal produced by a second RF source coupled to an RF antenna adjacent to the first RF antenna is greater than 10 kHz.
