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. Web1 jan. 2024 · Lithography is the collective name for different patterning techniques utilized in device fabrication. Photolithography is the most common lithography technique where a photoresist film is first patterned by UV light exposure through a mask.

Indeed, when one takes into account the dark erosion rate (~5 nm/min) and the rather long development times, the minimum feature size becomes approximately 430 nm [17]. The use of a negative resist is an interesting route to surpass such limitations. photo of cindy williams
