Abstract :
Recent results concerning selective vapor-phase silylation on conventional photoresists and subsequent pattern delineation of modified resists using reactive ion etching are presented. Four resist design guidelines for improved image contrast and resolution in submicron silylation lithography are introduced, the key mechanisms are discussed, the nonlinear resist development behavior is described, and an integrated model for selective silylation lithography is presented
