Polymethacrylates with tert-alcohol ester were synthesized as negativetone chemical amplification photoresists (CAMPs) for 193-nm microlithography. The acid-catalyzed dehydration reaction of the CAMPs was analyzed via Fourier transform infrared. The crosslinking behavior following the dehydration re
## Abstract Novel waterβdevelopable negative resists were designed to induce both crosslinking and polarity change upon exposure and bake. The matrix polymers were synthesized by copolymerization of glyceryl methacrylate and methacrolein. The acidβcatalyzed acetalization of the polymer induced cros
Optical lithography continues to be investigated as the most interesting approach for achieving sub 0.18 ~tm design rules. Currently an important effort is going on for single layer resist optimization at 193 nm, while some work is also performed to investigate the potential of top surface imaging s
