Abstract:
A method for processing a workpiece with a focused particle beam system comprising the steps ofproviding a particle beam system including providing a work stage assembly adapted a) for supporting the workpiece, b) for translating the workpiece along a first axis, c) for translating the workpiece along a second axis perpendicular to the first axis, and d) for rotating the workpiece about a third axis perpendicular to both the first axis and the second axis, said work stage assembly having a work stage axis substantially parallel to the third axis, and providing a first particle beam source for etching and imaging the workpiece, the first particle beam source having a first particle beam axis, oriented to form an acute angle with the third axis, such that the particle beam system can etch and image a vertical cross-section of the workpiece without offsetting the work stage axis from the third axis, placing a workpiece on said work stage assembly, and etching a first cavity in the workpiece using said first particle beam source to expose at least a portion of at least one structure contained in a vertical cross-section of the workpiece.
