  • Focused ion beam systems and methods of operation
    Patent number: 9576767
    Abstract: A focused ion beam system is provided. The focused ion beam system includes a plasma generation chamber configured to contain a source gas that is radiated with microwaves to produce plasma. The plasma generation chamber includes a plasma confinement device configured to confine the plasma in radial and axial directions within the plasma generation chamber and to form a plasma meniscus at an extraction end of the plasma generation chamber. The focused ion beam system also includes a beam extraction chamber configured to extract a focused ion beam from the confined plasma and to focus the extracted focused ion beam on a workpiece.
    Type: Grant
