An i-line molecular glass photoresist for high resolution patterning†
Abstract
Calix[4]resorcinarene was functionalized by photoactive 2-diazo-1-naphthoquinone-4-sulfonyl chloride (2,1,4-DNQ-Cl) to form a single-component non-chemically amplified i-line molecular glass photoresist. This single-component molecular glass photoresist afforded clean 100 nm line patterns with i-line interference lithography.
