==Deposition of aluminium oxide==
==Deposition of aluminium oxide==
Aluminium oxide (Alumina, Al<sub>2</sub>O<sub>3</sub> ) can be deposited by use of ALD (atomic layer deposition) or by a sputter technique in the [[Specific Process Knowledge/Thin film deposition/Lesker|Lesker Sputter System]]. During the sputter deposition oxygen is added to the chamber resulting in aluminium oxide on the sample.
