摘要: Methods for fabricating gate electrode/high-k dielectric structures having an improved resistance to the growth of silicon dioxide (oxide) at dielectric/silicon-based substrate interface. In embodiment, a method forming transistor structure comprises: incorporating nitrogen into silicon-based proximate surface substrate; depositing high-k across and electrode form structure. one comprises titanium nitride rich in inhibiting diffusion oxygen.
