Specific Process Knowledge/Thin film deposition/Deposition of Titanium Oxide

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 technique Lesker
Stoichiometry	Can probably be varied (sputter target: Ti, O2 added during deposition)
Film thickness	~10nm - ~0.5µm(>2h)	Thin layers
Deposition rate
Process Temperature	Expected to be below 100oC
Step coverage	Not Known
Film quality
Batch size	1 50mm wafer 1 100mm wafer 1 150mm wafer 1 200mm wafer Smaller pieces can be mounted with capton tape
Material allowed	Almost any materials not Pb and very poisonous materials
