Webpound in positive resists, with a lower development rate and higher dark erosion as a conse-quence. Negative resists will suffer from thermal cross-linking during baking, which lowers the development rate or makes through-development impossible. Generally, we recommend a softbake at 100°C on a hotplate for 1 minute per µm resist film thickness. Web5 jul. 2016 · Enhanced patterning by tilted ion implantation.
