Claim 6:
7. A multi-charged-particle-beam writing apparatus comprising:
a writer 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, each rectangular region including a plurality of pixels each having a predetermined size and arranged in a mesh; and
a controller controlling the writer such that 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.
