As 193nm immersion lithography is extended to sub-40nm technology node, how to define a single-pass contact hole patterning process with enough common lithography process window is a very challenging task. Sub-resolution assist features (SRAF) optimi

Many methods exist for imputing missing data but fewer methods have been proposed to test the missing data mechanism. Little (1988) introduced a multivariate chi-square test for the missing completely at random data mechanism (MCAR) that compares obs
