Abstract

This defect-based study analyzes statisticalsignal delay properties and delay fault test patternconstraints in the CMOS deep submicron environment.Delay fault testing has uncertainty, or noise, in its attemptto detect defects that slow a signal.CMOS resistive viasand contacts were used as a delay defect target.Datawere taken from a scan-based test chip (Veqtor) on thePhilips 0.25 µm technology.Methods to improve delayfault defect detection are given.
