Fully-depleted SOI CMOS technology using WXN metal gate and HfSixOyNZ high-k dielectric

This paper describes the fabrication and electrical behavior of a fully-depleted SOI technology using a direct metal gate and high-k dielectric integrated on 300 mm SOI wafers for low power applications. We report ultra-thin FDSOI MOS transistors with WN metal gate (capped with TiN) on HfSiON gate dielectric. Performance at both device and circuit level are demonstrated and compared with TiN midgap metal gate.
