*Al:N:O ~ 53 : 46 : 1.5 in the bulk (see acceptance test results [[Specific_Process_Knowledge/Thin_film_deposition/Cluster-based_multi-chamber_high_vacuum_sputtering_deposition_system#Process information|here]]). It should be possible to tune the Al:N ratio somewhat.

*[[Specific_Process_Knowledge/Thin_film_deposition/Cluster-based_multi-chamber_high_vacuum_sputtering_deposition_system#Process information|Deposition conditions and acceptance test results]] for sputter deposition of AlN in the Sputter-System Metal-Nitride(PC3).
*For further information on AlN deposition using the sputter systems please contact the Thin Film Group ([mailto:thinfilm@nanolab.dtu.dk thinfilm@nanolab.dtu.dk]). The Sputter-System Metal-Nitride(PC3) was acquired partly to make it possible to deposit high-quality of AlN films.
