Abstract

We report a novel 1000°C stable HfLaON p-MOSFET with Ir3Si gate. Low leakage current of 1.8 × 10-5 A/cm2 at 1 V above flat-band voltage, good effective work function of 5.08 eV, and high mobility of 84 cm2/V · s are simultaneously obtained at 1.6 nm equivalent oxide thickness. This gate-first p-MOSFET process with self-aligned ion implant and 1000°C rapid thermal annealing is fully compatible to current very large scale integration fabrication lines.
