APPARATUS AND METHOD FOR CONTROLLED PARTICLE BEAM MANUFACTURING

摘要

A chamber (102 in Fig. 2) for exposing a workpiece to charged particles (101 in Fig. 2) includes a source, a collimator, a beam digitizer (230 in Fig. 2) downstream of the collimator configured to create a digital beam including groups of at least one charged particle (Fig. 3B and 5) by adjusting longitudinal spacing between the particles along the axis, a deflector (210 in Fig. 6A and 6B) downstream of the beam digitizer including a series of deflection stages disposed longitudinally along the axis to deflect the digital beams, and a workpiece stage downstream of the deflector configured to hold the workpiece.
