Abstract:
In one embodiment, a multi charged particle beam writing apparatus includes a shaping aperture array forming multiple beams by allowing part of a charged particle beam to pass through a plurality of first openings, a blanking aperture array having a plurality of second openings having respective blankers each configured to deflect and blank the beam passing therethrough, a stopping aperture member having a third opening and configured to block deflected beams of the multiple beams at a position off the third opening, a first alignment coil disposed between the blanking aperture array and the stopping aperture member and adjusting a beam path, an objective lens disposed between the stopping aperture member and a stage, and a movement controller controlling a movement of a position of the third opening in an in-plane direction of the stopping aperture member.

Claim (Index 4):
A multi charged particle beam adjusting method comprising:\n emitting a charged particle beam; forming multiple beams by using a shaping aperture array having a plurality of first openings, being irradiated with the charged particle beam in a region including the plurality of first openings, and allowing part of the charged particle beam to pass through the plurality of first openings; measuring an amount of in-plane displacement of a beam position by varying excitation of an objective lens configured to adjust a path of the multiple beams, the multiple beams passing through a plurality of second openings in a blanking aperture array and a third opening in a stopping aperture member placed at an initial position; and adjusting a beam path in such a manner that by moving the third opening to a position where the amount of in-plane displacement of the beam position is minimized, the beams passing through the third opening pass through a center of the objective lens.
