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 1):
A multi charged particle beam writing apparatus comprising:\n an emitter emitting a charged particle beam; a shaping aperture array having a plurality of first openings, irradiated with the charged particle beam in a region including the plurality of first openings, and forming multiple beams by allowing part of the charged particle beam to pass through the plurality of first openings; a blanking aperture array having a plurality of second openings each configured to allow a corresponding beam of multiple beams passing through the plurality of first openings to pass therethrough, the plurality of second openings having respective blankers each configured to deflect 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, the deflected beams being deflected by the blankers in such a manner as to be turned off, the stopping aperture member being configured to allow beams in an on-state to pass through 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 configured to hold thereon a substrate subjected to writing with the beams; and a movement controller controlling a movement of a position of the third opening in an in-plane direction of the stopping aperture member.
