  • Patent number: 11948781
    Abstract: A processing system may include a plasma chamber operable to generate a plasma, and an extraction assembly, arranged along a side of the plasma chamber. The extraction assembly may include an extraction plate including an extraction aperture, the extraction plate having a non-planar shape, and generating an extracted ion beam at a high angle of incidence with respect to a perpendicular to a plane of a substrate, when the plane of the substrate is arranged parallel to the side of the plasma chamber.

  • Publication number: 20040079289
    Abstract: An apparatus for processing a semiconductor wafer. The apparatus according to the present invention comprises a wafer port flange including an electrostatic chuck and a top plate including a lip. The electrostatic chuck defines a circumferential gas distribution groove and a gas gap positioned between a backside of a semiconductor wafer and the electrostatic chuck. The lip is positioned to shield an outside band of the wafer. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR §1.72(b).

  • Patent number: 6305316
    Abstract: A wafer processing system is provided. The system includes a wafer handling system for introducing semiconductor wafers into a processing chamber. An oscillator is operatively coupled to an antenna for igniting a plasma within the processing chamber. The plasma and antenna form a resonant circuit with the oscillator, and the oscillator varies an output characteristic associated therewith based on a load change in the resonant circuit during plasma ignition.
