  • Patent number: 11651932
    Abstract: An ion source capable of extracting a ribbon ion beam with improved vertical angular uniformity is disclosed. The extraction plate and extraction optics are designed such that there is at least one non-uniform gap between adjacent components. A non-uniform gap may be effective in reducing angular spread non-uniformity of the extracted ribbon ion beam. Specifically, for a given gap in the Z direction, ions extracted from regions with lower plasma density may have more vertical angular spread. A larger gap in the Z direction between components in this region may make the vertical angular spread closer to the vertical angular spread of ions extracted from regions with higher plasma density. The non-uniform gap may be created by having an extraction plate that is flat or curved and electrodes that are flat, convex or concave. In certain embodiments, the non-uniform gap is located between the extraction plate and the suppression electrode.

    Abstract: An ion source with a target holder for holding a solid dopant material is disclosed. The ion source comprises a thermocouple disposed proximate the target holder to monitor the temperature of the solid dopant material. In certain embodiments, a controller uses this temperature information to vary one or more parameters of the ion source, such as arc voltage, cathode bias voltage, extracted beam current, or the position of the target holder within the arc chamber. Various embodiments showing the connections between the controller and the thermocouple are shown. Further, embodiments showing various placement of the thermocouple on the target holder are also presented.

  • Patent number: 11069511
    Abstract: A system having an auxiliary plasma source, disposed proximate the workpiece, for use with an ion beam is disclosed. The auxiliary plasma source is used to create ions and radicals which drift toward the workpiece and may form a film. The ion beam is then used to provide energy so that the ions and radicals can process the workpiece. Further, various applications of the system are also disclosed. For example, the system can be used for various processes including deposition, implantation, etching, pre-treatment and post-treatment. By locating an auxiliary plasma source close to the workpiece, processes that were previously not possible may be performed. Further, two dissimilar processes, such as cleaning and implanting or implanting and passivating can be performed without removing the workpiece from the end station.

  • Patent number: 10914800
    Abstract: Technologies relating to a magnetic resonance spectrometer are disclosed. The magnetic resonance spectrometer may include a doped nanostructured crystal. By nanostructuring the surface of the crystal, the sensor-sample contact area of the crystal can be increased. As a result of the increased sensor-sample contact area, the output fluorescence signal emitted from the crystal is also increased, with corresponding reductions in measurement acquisition time and requisite sample volumes.

  • Patent number: 10886135
    Abstract: In a substrate processing method, electrons having a first energy are supplied from an electron beam generator into an inner space of a chamber body of a substrate processing apparatus to generate negative ions by attaching the electrons to molecules in a processing gas supplied to the inner space. Then a positive bias voltage is applied to an electrode of a supporting table that supports a substrate mounted on thereon in the inner space to attract the negative ions to the substrate.
