Stochastic Model for Acid Diffusion in DUV Chemically Amplified Resists 1

Recent articles have focused much effort on studying the stochastic behavior of secondary electron exposure of EUV resists [1-4]. Here, we consider the implications of extending similar treatments to DUV lithography.

Basic Model Setup

As before, the model uses pixel-by-pixel calculations of absorbed photon dose, followed… Read More
