Claim 0:
1. A multi-charged-particle-beam writing method comprising:
performing a tracking operation such that, while a substrate placed on a stage moving continuously is being irradiated with multiple beams including a plurality of charged particle beams, deflection positions of the multiple beams follow movement of the stage; and
applying the multiple beams to the substrate having a writing area including a plurality of rectangular regions arranged in a mesh during the tracking operation such that each of the plurality of rectangular regions is irradiated with the multiple beams,
wherein each rectangular region includes a plurality of pixels each having a predetermined size and arranged in a mesh, and
wherein at least one subset of the plurality of pixels is irradiated with the multiple beams in a first shot order and is then irradiated with the multiple beams in a second shot order different from the first shot order.
