Webmask. 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. WebJun 1, 2003 · 1..
