Lithography dark erosion
Webin a dark room. Now you can compare the visible result of the Litho-protect® light with your current yellow room illumination, using the yellow light indicator. We would be pleased to … 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.
