Abstract:
1. A direct-write (DW) system, comprising: a stage for holding a substrate and operable to scan the substrate; a data processing module for processing pattern data and generating instructions associated with the pattern data; and an exposure module that includes a plurality of beams that are focused onto the substrate and a beam controller that controls the plurality of beams in accordance with the instructions while the substrate is scanned; wherein the data processing module includes a plurality of vertex pair processors each having a plurality of bit inverters, wherein each vertex pair processor is operable to process a respective vertex pair of an input scan line to generate an output scan line, wherein each bit inverter is operable to invert a respective input bit of the input scan line to generate a respective output bit of the output scan line if a bit position is located between the respective vertex pair, wherein each bit inverter is operable to copy the respective input bit of the input scan line to generate the respective output bit of the output scan line if the bit position is located outside of the respective vertex pair, wherein the respective input bit is obtained from a previous scan line; wherein the instructions correspond to the output bits of the output scan line for each beam.
