WebDec 19, 2006 · Abstract Although scarcely used before 1972, chlororaethylstyrenes (ortho, meta, and para) have been the subject of an increasing number of publications and patents since then: 5 publications in 1972, 22 in 1973, 29 in 1976. The yearly average is now about 40 publications. Related research WebIn chloromethylstyrene-based blend resists, almost the same sensitivity improvement as that for copolymer resists is obtained. Furthermore, the y value does not depend on the dispersivity of blend systems, but depends on the dispersivity of the higher molecular weight polymer with stronger electron donating ring-substituents.
