Deposition of Aluminium Nitride

AlN can be deposited by using sputtering method with AlN target or reactive sputtering method with Al target in mixtures of argon and nitrogen. AlN film can be deposited by using the Cryofox PVD co-sputter/evaporation or the Lesker Sputter System.



Only one method at the moment

Cryofox PVD co-sputter/evaporation Sputter System Lesker
