Abstract
A MOS transistor is formed with a dual-layer silicon oxynitride (SiON) etch stop film that protects the transistor from plasma induced damage (PID) and hot carrier degradation, thereby improving the reliability of the transistors. The first SiON layer is formed with SiHat a first flow rate, and the second SiON layer is formed with SiHat a second higher flow rate.
