To re-iterate, the consequence of increasing PEB on the overall lithographic behaviour of Medusa 82 is manifested in augmented deviation from nominal design values, although this can be mitigated by using lower exposure dose.

Web5 aug. 2014 · A post-exposure baking (PEB) process was applied at 80 °C for 1 min in order to investigate the influence of the PEB process. The exposed resist films were developed in a 7:3 IPA/DI water mixture for 1 min followed by … 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.
WebAfter PEB and after develop resist thickness is shown in Figure 1 for a model NTD system from Dow [9]. As shown in the igure, F about 15nm of thickness loss is seen after PEB at high exposure dose values. After develop, an additional 15nm of resist loss is also observed. From this simple experiment, it is clear that accurate cross-section Web26 feb. 2024 · As EUV lithography systems are now being used in high volume manufacturing by leading-edge chipmakers, further improvements to productivity and resolution will help extend affordable scaling to future process nodes.
