Proximity effect reduction in high voltage electron‐beam lithography by bias exposure method
TL;DR: In this paper, the bias exposure was used to reduce the pattern size error for high voltage and high voltage electron beam (EB) uniform exposure (bias exposure) on the target covered with PMMA resist of 1 μm in addition to conventional high voltage EB writing.
