Synopsis

A technique for determining radiation chemical yields from lithographic exposure curves for crosslinking type negative electron beam resists has been extended to include polymers with a general Poisson distribution. The technique is applied to several different chlorine-containing styrene-based resists. The radiation yields show good agreement with the differences in lithographic sensitivity and are explained by recent mechanistic studies. Optimal synthetic approaches for preparing this type of resist are described.

Although chlorinated paraffins (CP) are produced in large amounts (300000 tonnes per year), little is known about their occurrence in the environment due to the lack of specific and sensitive analytical methods. The present paper describes the GC/MS analysis of different CP's using capillary gas chr
