Abstract
A method of preventing toxic gas formation after an implantation process is disclosed. Certain dopants, when implanted into films disposed on a substrate, may react when exposed to moisture to form a toxic gas and/or a flammable gas. By in-situ exposing the doped film to an oxygen containing compound, dopant that is shallowly implanted into the layer stack reacts to form a dopant oxide, thereby reducing potential toxic gas and/or flammable gas formation. Alternatively, a capping layer may be formed in-situ over the implanted film to reduce the potential generation of toxic gas and/or flammable gas.
