Device design considerations for double-gate, ground-plane, and single-gated ultra-thin SOI MOSFET's at the 25 nm channel length generation

Abstract

We present a simulation-based analysis of device design at the 25 nm channel length generation. Double-gate, ground-plane, and single-gated ultra-thin SOI MOSFET's are considered. Dependencies of short-channel effects on channel thickness and ground-plane bias are illustrated. Two-dimensional field effects in the gate insulator (high k) and the buried insulator (low k) in single-gate SOI are studied.
