Deposition of Titanium Oxide

Titanium oxide can be deposited only by sputter technique. At the moment the only system where we have a target for Titanium oxide is IBE/IBSD Ionfab300. The target is Ti. During the sputter deposition oxygen is added to the chamber resulting in Titanium oxide on the sample.

Comparison of the methods for deposition of Titanium Oxide

	Sputter technique using IBE/IBSD Ionfab300	Sputter System Lesker
Generel description	TiO2 created from a Ti sputter target. By adding oxygen during the deposition TiO2 is created.	Generel description - method 2
