Abstract
A method and system for dose correction of a particle beam writer is disclosed. The method and system includes reading a file of writing objects that includes dose intensity, calculating a rate of dose intensity change between adjacent writing objects, selecting a writing object that may need accuracy improvement of dose correction based on the rate of dose intensity change, and improving accuracy of the dose correction of the writing object that is selected and its adjacent objects.
