The present invention, in one embodiment, relates to a process for fabricating a charge trapping dielectric flash memory device including steps of providing a semiconductor substrate having formed thereon a gate stack comprising a charge trapping dielectric charge storage layer and a control gate electrode overlying the charge trapping dielectric charge storage layer; forming an oxide layer over at least the gate stack; and depositing a spacer layer over the gate stack, wherein the depositing step deposits a spacer material having a reduced hydrogen content relative to a hydrogen content of a conventional spacer material.
