WebMar 16, 2024 · A photoresist is a light-sensitive polymer. When exposed to ultraviolet light, it turns to a soluble material. Those exposed areas can then be dissolved by using a solvent, leaving behind a pattern. While this has been done for years in semiconductor lithography, the problem is that the 193nm ArF light beam is too thick for sub-22nm designs to ...

Hereby, the resist sidewalls show a more or less pronounced undercut which makes the lift-off easier to realize. However, image reversal resists generally do not cross-link. Hence, from approx. 120-130°C on, the resist structures start to soften, and the features rounden making them less suited for lift-off. painel ripado no tetoWeb3.
