Paper Abstract

As the line-width goes sub-100 nm, process windows for al lithographic processes become smaller. Process control and monitoring of the process parameters become increasingly important and necessary as small variation in process variables such as exposure dose, temperature, resist thickness, developer concentration, etc. may cause the final critical dimension to differ from the specification.
