Paper Abstract

This paper presents the findings of a cationic surface active agent used to promote adhesion on an InGaAs multilayer system on GaAs. The improved adhesion of the HSQ resist allowed the electron exposure dose to be reduced by a factor of four, and enabled the production of features sizes down to 30nm. Moreover, the process latitude is greatly increased for both small and large lithographic features.
