Patent ID: 7791125

Claim:
A method of forming a semiconductor device, comprising: loading a semiconductor substrate into a reaction chamber; providing metal organic precursors including hafnium and zirconium into the reaction chamber; and forming a layer of hafnium-zirconium oxide (Hf x Zr 1-x O; 0<X<0.5) having a tetragonal crystalline structure on the semiconductor substrate; wherein forming the layer of hafnium-zirconium oxide having a tetragonal crystalline structure comprises: providing metal organic precursors including hafnium and zirconium into the reaction chamber; reacting the metal organic precursors including hafnium and zirconium with an oxidizer to form hafnium-zirconium oxide; and crystallizing the hafnium-zirconium oxide to have the tetragonal crystalline structure by performing a rapid thermal annealing process on the semiconductor substrate.
