    Abstract: A dual beam system includes an ion beam system and a scanning electron microscope with a magnetic objective lens. The ion beam system is adapted to operate optimally in the presence of the magnetic field from the SEM objective lens, so that the objective lens is not turned off during operation of the ion beam. An optional secondary particle detector and an optional charge neutralization flood gun are adapted to operate in the presence of the magnetic field. The magnetic objective lens is designed to have a constant heat signature, regardless of the strength of magnetic field being produced, so that the system does not need time to stabilize when the magnetic field is changed.

    Abstract: The present disclosure relates to a method for generating a three-dimensional microstructure in an object. In one embodiment, a method for fabricating a microscopic three-dimensional structure is provided. A work piece is provided that includes a target area at which the three-dimensional structure is to be fabricated. The target area has a plurality of virtual dwell points. A shaped beam is provided to project onto the work piece. The intersection of the shaped beam with the work piece defines a beam incidence region that has a desired shape. The beam incidence region is sufficiently large to encompass multiple ones of the virtual dwell points. The shaped beam is moved across the work piece such that different ones of the virtual dwell points come into it and leave it as the beam moves across the work piece thereby providing different doses to different ones of the virtual dwell points as the different dwell points remain in the beam incidence region for different lengths of time during the beam scan. In this way, a desired dose array of beam particles is applied onto the target area to form the three dimensional microstructure.
