Exploring the potential of Multiphoton Laser Ablation Lithography (MP-LAL) as a reliable technique for sub-50nm patterning. 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.

WebDark erosion is higher than with AZ 726 MIF, however this helps to avoid scumming, which mainly is observed when the photoresist is processed on steppers without … 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.
