Reliability of MOS devices with tungsten gates
Abstract
We have investigated the behaviour under accelerated reliability tests of MOS capacitors stressed at high voltage in accumulation with ultra-thin SiO 2 dielectrics and with tungsten gates. Standard p+ poly-Si gates are used as reference. In this report, we show and discuss data concerning the oxide wearout and the breakdown transient. © 2004 Elsevier B.V. All rights reserved.
