The data delivery throughput of electron beam lithography systems can be improved by applying lossless image compression
to the layout image and using an electron beam writer that can decode the compressed image on-the-fly. In earlier
research we introduced the lossless layout image compression algorithm Corner2, which assumes a somewhat idealized
writing strategy, namely row-by-row with a raster order. The MAPPER system has electron beam writers positioned in a
lattice formation and each electron beam writer writes a designated block in a zig-zag order. We introduce Corner2-MEB,
which redesigns Corner2 for MAPPER systems.
