Abstract
The degree to which critical performance parameters are stable against small variations in process parameters is called process latitude. Advanced computer models of UV microlithography are used to study the impact of the notching phenomenon (exposure enhancement near steps in the exposure plane) on process latitude. It is shown that notching effects give rise to a rapid degradation of resist development process latitude.<>
