Lithography dark erosion

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. Webcm2 making reproducible litho-processes impossible. Thus, a yellow filter with a transmission of 1 % below 500 nm wavelengths is not sui-ted to allow the storage of coated substrates for several hours at expo-sed places in the clean room near windows or fluorescent tubes. Under these conditions, positive resists will show an increased dark …
