Abstract
A method for writing a design to a material using an electron beam includes assigning a first dosage to a first polygonal shape. The first polygonal shape occupies a first virtual layer and includes a first set of pixels. The method also includes simulating a first write operation using the first polygonal shape to create the design, discerning an error in the simulated first write operation, and assigning a second dosage to a second polygonal shape to reduce the error. The second polygonal shape occupies a second virtual layer. The method further includes creating a data structure that includes the first and second polygonal shapes and saving the data structure to a non-transitory computer-readable medium.
