Unified model for physics-based modelling of a new device architecture: triple material gate oxide stack epitaxial channel profile (TRIMGAS Epi) MOSFET
Abstract:A new device architecture triple material gate oxide stack (TRIMGAS) epitaxial channel (Epi) MOSFET for reduced short channel effects (SCEs) at short gate lengths is proposed. The structure has a gate electrode consisting of three different materials, an oxide stack having high-K material on top of an SiO 2 layer and an epitaxial channel profile. A two-dimensional analytical threshold voltage and drain current model has been presented. An analysis of subthreshold slope and I-V characteristics has been done for… Show more
