The Impact of Strain Technology on FUSI Gate SOI CMOSFET

In this paper, the impact of strain engineering on device performance and reliability for fully silicide gate silicon-on-insulator CMOSFET was investigated. With characterizing device's electrical property after hot carrier (HC) and positive/negative bias instability voltage stressing, we found similar enhancement on device performance but different behavior on voltage-stressing-induced device degradation for n/pMOSFETs. Related noise analysis and charge pumping techniques were used to investigate the strain-induced oxide defect which will accelerate device degradation after long-time HC voltage stressing and/or bias instability voltage stressing.
