Abstract

The most important step in the processing of PBS electron beam resist is the development step. It has the greatest influence on the quality and appearance of the resist image. The purpose of this paper is to study the effect of developer concentration on PBS development/dissolution rate and resist image using optimized PBS resist coated mask blanks. The critical dimensions will be measured to determine the development rate and the image quality will be evaluated empirically. We'll be holding all other process variables constant.
