Paper Abstract

Decreasing feature size implies increased sensitivity to statistical fluctuations which impact critical dimension uniformity and control. In a recent work Gallatin and Liddle presented equations which describe the basic processes leading to surface and line edge roughness in a chemically amplified resists. Retaining only the lowest order terms in what is inherently a very nonlinear problem they were able to derive a scaling law and other dependencies which show reasonable agreement with experimental data. Here the analysis of the same equations is extended and expanded to include the dominant nonlinear effects.
