Abstract:
A semiconductor device and method of manufacturing same are described. A first hafnium oxide (HfO 2 ) layer is formed on a substrate. A titanium (Ti) layer is formed over the first hafnium oxide layer. A second hafnium oxide layer is formed over the titanium layer. The composite device structure is thermally annealed to produce a high-k dielectric structure having a hafnium titanium oxide (Hf x Ti 1-x O 2 ) layer interposed between the first hafnium oxide layer and the second hafnium oxide layer.

Claim (Index 9):
A semiconductor structure comprising:\n a semiconductor substrate; a hafnium oxide silicate layer directly on the semiconductor substrate; a first hafnium oxide layer directly contacting the hafnium oxide silicate layer; a hafnium titanium oxide layer directly contacting the first hafnium oxide layer; a second hafnium oxide layer directly contacting the hafnium titanium oxide layer, wherein the hafnium oxide silicate layer, the first hafnium oxide layer, the hafnium titanium oxide layer and the second hafnium oxide layer collectively form a composite gate dielectric; and a gate electrode overlying the composite gate dielectric, wherein the composite gate dielectric is interposed between the gate electrode and the semiconductor substrate.
