摘要
In general the writing strategies of the Leica ZBA 320 tool are presented to the audience. Methods to achieve a high productivity in writing masks of the next generation are highlighted. Thus, such writing modes like variable-shaped beam (VSB) using 6 shape types, vector scan and "writing-on-the-fly" are explained in their inter-action. Our strategies to constantly improve the accuracy parameters, such like n-pass writing and soft boundaries are not only described but also illustrated by our latest application results. Finally data processing by hierarchical data structures as the main factor to support the above-mentioned writing strategies is outlined in this paper.
