Abstract:
A chicane blanker assembly for a charged particle beam system includes an entrance and an exit, at least one neutrals blocking structure, a plurality of chicane deflectors, a beam blanking deflector, and a beam blocking structure. The entrance is configured to accept a beam of charged particles propagating along an axis. The at least one neutrals blocking structure intersects the axis. The plurality of chicane deflectors includes a first chicane deflector, a second chicane deflector, a third chicane deflector, and a fourth chicane deflector sequentially arranged in series between the entrance and the exit and configured to deflect the beam along a path that bypasses the neutrals blocking structure and exits the chicane blanker assembly through the exit. In embodiments, the chicane blanker assembly includes a two neutrals blocking structures. In embodiments, the beam blocking structure is arranged between the third chicane deflector and the fourth chicane deflector.
