Abstract

A thermal oxidation method for forming a gate dielectric layer for use within a field effect transistor device employs a thermal oxidizing atmosphere comprising a halogen getter material. By employing the halogen getter material, the field effect transistor device is formed with enhanced performance, in particular with respect to negative bias temperature instability lifetime.
