Title
Influence of Gate Length on pBTI in GaN-on-Si E-Mode MOSc-HEMT
Abstract
In this paper, we explore the influence of the fully recessed gate length on threshold voltage instabilities. The study has been performed by the use of ultra-fast pBTI measurements on GaN-on-Si E-mode MOSc-HEMTs, as well as TCAD simulations. It reveals that gate length reduction tends to decrease the pBTI degradation. Transient analyses (degradation/relexation) reveal same dynamics whatever the gate length while the value of the initial V <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TH</inf> directly influences BTI. TCAD simulations highlight that the full recess gate configuration creates a short-channel effect responsible for this peculiar Vth degradation.
