1. A method for exposing a pattern in an area on a surface using charged particle beam lithography, the method comprising:
inputting an original set of exposure information for the area, wherein the area comprises a plurality of pixels, and wherein the original set of exposure information comprises dosages for the plurality of pixels in the area;
calculating a backscatter for a sub area of the area, based on the original set of exposure information including the dosages for the plurality of pixels in the area; and
determining an increase in dosage for at least one pixel in a plurality of pixels in the sub area, in a location where the backscatter of the sub area is below a pre-determined threshold, thereby increasing the backscatter of the sub area.
