METHOD FOR ELIMINATING LOW FREQUENCY ERROR SOURCES TO CRITICAL DIMENSION UNIFORMITY IN SHAPED BEAM WRITING SYSTEMS

摘要

A method and system for generating flashes on a substrate. The method includes receiving one or more figures of a pattern to be printed on the substrate and decomposing each figure into at least four substantially rectangular shapes. The four substantially rectangular shapes are separated by at least one horizontal boundary and at least one vertical boundary. The method further includes generating a flash for each substantially rectangular shape such that each edge of each figure is an image of the same aperture.
