28 August 1998 Simulation of charging voltages on a wafer during plasma etch
Author Affiliations +
During plasma etching, the dependence of gate oxide damage on die location and polarity of the charging voltage will yield devices with varying damage across a wafer. This paper describes a simulator capable of estimating the charging voltage across the gate oxide for any location on a wafer. This tool will enable reliability and process engineers to monitor the damage and identify regions of worst-case damage on a wafer for further testing.
