Patent ID: 8878141

Claim:
A drawing apparatus which performs drawing on a substrate with a plurality of charged particle beams, the apparatus comprising: a stage configured to hold the substrate and to be moved; a charged particle optical system including a deflector configured to deflect the plurality of charged particle beams; a detector configured to detect a charged particle arrived thereat by causing a charged particle beam to impinge on a mark including first and second mark elements formed on one of the substrate and the stage with the charged particle beam undergoing deflection thereof by the deflector; and a processor configured to perform a process of obtaining a position of the mark, wherein the processor is configured to control the stage, the charged particle optical system, and the detector such that a position of the first mark element is measured while two ends of the first mark element fall within a range of deflection by the deflector with respect to a first charged particle beam among the plurality of charged particle beams, and a position of the second mark element, different from the first mark element, is measured while two ends of the second mark element fall within a range of deflection by the deflector with respect to a second charged particle beam, among the plurality of charged particle beams, closer to the second mark element than the first charged particle beam.
