Abstract: A method for mitigating moisture driven degradation of silicon doped chalcogenides includes placing a silicon doped chalcogenide composition in a process chamber, passivating dangling silicon bonds of the silicon doped chalcogenide composition by flooding the process chamber with forming gas or with hydrogen plasma, purging the forming gas or the hydrogen plasma from the process chamber, and removing the passivated silicon doped chalcogenide composition from the process chamber.
