Claim 12:
13. An apparatus, comprising:
an optical source configured to produce a processing beam having a predetermined beam diameter;
an optical system situated to receive the processing beam from the optical source;
a substrate stage adapted to retain a substrate; and
a scan controller configured to receive a scan pattern defined as a plurality of scan vectors and control at least one of the optical system and the substrate stage so that the processing beam is directed to a scan area of the substrate with a predetermined beam diameter to produce exposed scan vectors in the scan area such that transverse offsets between the exposed scan vectors and intended scan vectors are less than 1/10 of the predetermined beam diameter based on beam deflection angles defined by a number of bits used to determine beam deflections and a focal plane distance.
