A fast path-based method for 3-D resist development simulation
A new and efficient resist development simulation method has been developed for simple patterns. The new method has been compared with two widely used methods: cell removal method and fast marching method. The new method achieves high accuracy, even for more general patterns, while requiring much less computation and memory. The new method is fast enough to be used in an iterative proximity effect correction (PEC) scheme.
