제목 Negative Molecular Resists with Calix[4]resocinarene for DUV Lithography
초록 A negative working molecular resists based on fully epoxy-protected tetra-Cmethylcalix[4]resorcinarene (epoxy C-4-R) has been developed. Epoxy C-4-Rs were prepared by the reaction of C-4-R with epichlorohydrin in the presence of trimethylamine. They can be coated on the silicon wafer by spin-coating method. A clear film cast from a 20 wt% epoxy C-4-R solution in chloroform showed high transparency to UV above 300 nm. A fine positive image featuring 0.8 μm of minimum line and space patterns was observed on the film of the photoresist exposed to 40 mJ/ cm2 of DUV-light by the contact mode.
