Webknown as dark erosion [19], which severely limits the prospect of single domain structures. 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. Webi) With increasing developer concentration, the dark erosion rate growths faster than the development rate. The KOH-based AZ® 400K and NaOH-based AZ® 351B are typically applied in a 1 : 4 dilution with water. AZ® Developer can be applied as a concentrate (high development rate), or in a 1 : 1 dilution (improved selectivity).
