摘要:
Disclosed herein are various embodiments of semiconductor devices and related methods of manufacturing a semiconductor device. In one embodiment, a method includes providing a semiconductor substrate and forming a metal silicide on the semiconductor substrate. In addition, the method includes treating an exposed surface of the metal silicide with a hydrogen/nitrogen-containing compound to form a treated layer on the exposed surface, where the composition of the treated layer hinders oxidation of the exposed surface. The method may then further include depositing a dielectric layer over the treated layer and the exposed surface of the metal silicide.
