Paper Abstract

In this paper, we present our approaches to solve the delay problem, i.e., the formation of T- tops during the delay time between exposure and post-exposure bake. We investigated the distribution of the photoacid generator in the resist layer and the influence of basic contaminations in the formulation. T-topped patterns can be avoided by using appropriate developers. The incorporation of additives make the resist less sensitive to basic contaminations. Some formulations show no T-top formation under severe conditions for a considerable amount of time.
