Abstract
Corrugated silicon nitride masks (SiNMs) with improved mechanical strength are developed for patterning OLED microdisplays. The corrugations in the nitride membrane significantly increase the rigidity of the mask and reduce sagging, enabling 3000-ppi slot apertures for patterning RGB-stripe pixel layouts that are normally not achievable by fine metal masks.
