Paper Abstract

Excimer laser lithography combined with chemically amplified resists offers a viable approach to lithography at 0.5 micrometers and below. APEX-E, a positive tone deep-uv resist used in conjunction with a 0.44 NA excimer laser stepper is capable of 0.35 micrometers resolution. To improve the process window for this resist while reducing the performance variability, the Taguchi method of quality control was employed. The baseline process for APEX-E was characterized, then subsequently used as a comparison to the optimized process as suggested by the Taguchi experiments.
