Semiconductor device having fluorine bearing sidewall spacers and method of manufacture thereof

摘要

Fluorine bearing spacers on the sidewalls of gate electrodes of a semiconductor device are provided to suppress hot carrier injection in the semiconductor device. In accordance with one embodiment of the invention, a semiconductor device is formed by forming at least one gate electrode on a surface of a substrate and forming fluorine bearing spacers on the sidewalls of the gate electrode. The fluorine bearing spacers may, for example, be formed of an NF3-doped glass material.
