Paper Abstract

The binary lithography combined with precise control of RIE (Reactive Ion Etch) could fabricate an 8-level blazed grating with the reflective efficiency above 80% in recent years. The pixel size of the 8-level grating is often designed to be 32 microns or even larger due to the manipulation error of the mask-aligner. By the excellent augmentation of the mask-stepper, which is popular in IC industry, the smaller pixel size or the higher-order levels of the gratings could be achieved ideally.
