The ALD window for depostion of Titanium oxide ranges from 120 oC to 350 oC. XPS measurements shows that at temperatures below 120 oC the TiO3 layer will be contaminated by Cl molecules.

All results shown on this page have been obtained using the "TiO2" recipe on new Si(100) wafers with native oxide:


Recipe: TiO2

Temperature: 150 oC - 350 oC
