    摘要: A plasma processing tool comprises a plasma chamber configured to generate a plasma from a gas introduced into the chamber where the generated plasma has an electron plasma frequency. A plurality of electrodes disposed within the chamber. Each of the electrodes configured to create a rapidly-rising-electric-field pulse in a portion of the plasma contained in the chamber. Each of said rapidly-rising-electric-field pulses having a rise time substantially equal to or less than the inverse of the electron plasma frequency and a duration of less than the inverse of the ion plasma frequency. In this manner, the electron energy distribution in the generated plasma may be spatially and locally modified thereby affecting the density, composition and temperature of the species in the plasma and consequently the uniformity of the density and composition of ions and neutrals directed at a target substrate.

    摘要: An electrode assembly for use with an ion source chamber or as part of an ion implanter processing system to provide a uniform ion beam profile. The electrode assembly includes an electrode having an extraction slot with length L aligned with an aperture of the ion source chamber for extracting an ion beam. The electrode includes a plurality of segments partitioned within the length of the extraction slot where each of the segments is configured to be displaced in at least one direction with respect to the ion beam. A plurality of actuators are connected to the plurality of electrode segments for displacing one or more of the segments. By displacing at least one of the plurality of electrode segments, the current density of a portion of the ion beam corresponding to the position of the segment within the extraction slot is modified to provide a uniform current density beam profile associated with the extracted ion beam.

    摘要: A Faraday dose and uniformity monitor can include a magnetically suppressed annular Faraday cup surrounding a target wafer. A narrow aperture can reduce discharges within Faraday cup opening. The annular Faraday cup can have a continuous cross section to eliminate discharges due to breaks. A plurality of annular Faraday cups at different radii can independently measure current density to monitor changes in plasma uniformity. The magnetic suppression field can be configured to have a very rapid decrease in field strength with distance to minimize plasma and implant perturbations and can include both radial and azimuthal components, or primarily azimuthal components. The azimuthal field component can be generated by multiple vertically oriented magnets of alternating polarity, or by the use of a magnetic field coil. In addition, dose electronics can provide integration of pulsed current at high voltage, and can convert the integrated charge to a series of light pulses coupled optically to a dose controller.
