PATTERN LOCK SYSTEM FOR PARTICLE-BEAM EXPOSURE APPARATUS |
摘要 |
<p>In a pattern-lock system of particle-beam apparatus wherein the imaging of the pattern is done by means of at least two consecutive projector stages of the projecting system, reference marks are imaged upon registering means to determine the position of the particle-beam, at the location of an intermediary image of the reference marks produced by a non-final projector stage, with the registering means being positioned at locations of nominal positions of an intermediary imaging plane. Furthermore, to produce a scanning movement over the registering means the reference beamlets are shifted laterally by means of deflector means provided in the pattern defining means in dependence of a time-dependent electric voltage.</p> |
