WebThus, the erosion of the exposed resist during development is rather high, the resist starts thinning. An exposure dose too high also illuminates nominal dark re-sist areas via scattering, diffraction, or reflection. As a consequence, the resist structures re-maining after development are much larger than determined by the photomask. 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.
