Abstract :
This paper introduces a new method, contrast enhancement, which improves the imaging properties of conventional photoresist through the use of a photobleachable layer applied to the resist surface. Contrast enhancement allows high contrast photopatterns to be formed even when low contrast illumination is used. A short discussion of the theory and an experimental demonstration of the method are presented.
