WebIOPscience WebPEB sensitivity is defined as the dependency of pattern size (or critical dimension, CD) variation on the perturbation of the PEB temperature and time throughout this paper. From the beginning of ArF (193 nm) lithography, PEB sensitivity becomes serious problem because ArF photoresist shows very severe dependency on PEB temperature and time.
