摘要:
Methods of forming rutile titanium dioxide. The method comprises exposing a transition metal (such as V, Cr, W, Mn, Ru, Os, Rh, Ir, Pt, Ge, Sn, or Pb) to oxygen gas (O2) to oxidize the transition metal. Rutile titanium dioxide is formed over the oxidized transition metal. The rutile titanium dioxide is formed by atomic layer deposition by introducing a gaseous titanium halide precursor and water to the oxidized transition metal. Methods of forming semiconductor structures having rutile titanium dioxide are also disclosed.
