Patent ID: 8748064

Claim:
A charged particle beam drawing method for drawing measurement patterns on a mask based on control data outputted from a storage unit, the mask having a plurality of stripes set therein, the stripes each having a plurality of main deflection fields in each of which N×M measurement patterns are to be formed respectively in a plurality of measurement pattern areas, the charged particle beam drawing method comprising the steps of: forming a first measurement pattern in a first measurement pattern area; in succession with processing of forming the first measurement pattern, forming a second measurement pattern in a second measurement pattern area located farthest from the first measurement pattern area in the same column as the first measurement pattern area; and in moving a charged particle beam from the second measurement pattern area to a third measurement pattern area located adjacent to the first measurement pattern area in the same column as the first and second measurement patterns to form a third measurement pattern, moving the charged particle beam to the third measurement pattern area while taking tiny shots approximately equivalent to a data resolution at the adjacent measurement pattern areas to be drawn in the same column one after another from the second measurement pattern.
