Abstract
The chemistry of Photochemical Image Enhancement with anthracene photooxiidation is described in detail, emphasizing materials properties needed to avoid reciprocity failure due to oxygen depletion. The application of new materials, including dianthrylethanes and methacrylate-siloxane graft copolymers, is described; these are capable of providing exposure times of less than 1 sec, with the possibility of further improvements. The performance characteristics of existing materials have been compared to those of CEL by use of a simple analytical formula. Data are also presented on behavior in the deep UV, with a view toward application as CEL and PIE materials for DUV lithography.
