Abstract

In this work, we report the comprehensive study of performance enhancement of InGaAs n-MOSFET by plasma $PH_3$ p assivation. The calibrated plasma $PH_3$ passivation of the InGaA ssurface before CVD high-k dielectric deposition significantly improves interface quality, resulting in suppressed frequency dispersion in C-V, increase in drive-current with high electron mobility, and excellent thermal stability.
