MODULAR MICROWAVE SOURCE WITH EMBEDDED GROUND SURFACE
Embodiments disclosed herein include a source for a processing tool. In an embodiment, the source comprises a dielectric plate having a first surface and a second surface opposite from the first surface, and a cavity into the first surface of the dielectric plate. In an embodiment, the cavity comprises a third surface that is between the first surface and the second surface. In an embodiment, the source further comprises a dielectric resonator extending away from the third surface.
ECR ion source and method for operating an ECR ion source
An ECR (Electron Cyclotron Resonance) ion source includes a plasma chamber having a circular cylindrical cross-section, magnets for generating a magnetic field for confinement of the plasma in the plasma chamber, and a microwave generator disposed outside the plasma chamber and generating at least two microwave signals. Several antennas protrude radially into the plasma chamber with a predetermined angular offset α. The antennas receive phase-shifted microwave signals from the microwave generator and radiate linearly polarized microwaves, which in turn produce a circularly polarized microwave inside the plasma chamber. A method for operating an ECR ion source is also described.
APPARATUS AND SYSTEM INCLUDING EXTRACTION OPTICS HAVING MOVABLE BLOCKERS
Disclosed herein are approaches for adjusting extraction slits of an extraction plate using a set of adjustable beam blockers. In one approach, an ion extraction optics may include an extraction plate including a first opening and a second opening, and a first beam blocker extending over the first opening and a second beam blocker extending over the second opening. Each of the first and second beam blockers may include an inner slit defined by a first distance between an inner edge and the extraction plate, and an outer slit defined by a second distance between an outer edge and the extraction plate, wherein the first and second beam blockers are movable to vary at least one of the first distance and the second distance. As a result, extraction through the inner and outer slits of ion beamlets characterized by similar mean angles may be achieved.

Plasma source
The invention concerns a plasma source including a quarter wave antenna (204) located in a cylindrical enclosure (202) provided with an opening (208) opposite the end of the antenna (204). The diameter (d) of the antenna (204) is in the range from one third to one quarter of the inner diameter (d.sub.1) of the enclosure (202). The distance (l) between the end of the antenna (204) and the opening (208) is in the range from to 5/3 of the diameter (d) of the antenna (204).
Methods and systems for plasma deposition and treatment
This application is directed to an apparatus for creating microwave radiation patterns for an object detection system. The apparatus includes a waveguide conduit having first slots at one side of the conduit and corresponding second slots at an opposite side of the conduit. The waveguide conduit is coupled to a microwave source for transmitting microwaves from the microwave source through the plurality of first slots. A plunger is moveably positioned in the waveguide conduit from one end thereof. The plunger allows the waveguide conduit to be tuned to generally optimize the power of the microwaves exiting the first slots. Secondary plungers are each fitted in one of the second slots to independently tune or detune microwave emittance through a corresponding first slot.
