Simultaneous large-scale reliability analysis of ultra-thin MOS gate dielectrics using an automated test system

Abstract

Abstract. This article presents an automated test system targeting the large-scale analysis of ultra-thin MOS gate dielectric degradation. The system allows for stress tests at elevated temperatures as well as supply voltages and long-term tests of thousands of MOS devices simultaneously. The aim is to build-up large and hence significant statistics about the degradation process as a function of time.
