In summary, we developed a new ALD process to deposit high Al-content AlxTi1-xN by coevaporating dimethylamidometal complexes, TDMAA and TDMAT, and adding NH₃ plasma as the nitrogen source -offering an alternative to the more common super-cycle approach. We successfully deposited low impurity (<5 at.%) AlxTi1-xN thin films at temperatures as low as 200 °C. The cubic AlxTi1-xN phase could not be explicitly exhibited from our results, and more work needs to be done to improve the cubic phase and or minimize the hexagonal phases if these films are to be useable in hard coating applications. Our results suggest that TDMAA and TDMAT are promising precursors for low temperature/low-pressure co-evaporation ALD of AlxTi1-xN and more ternaries can be deposited using the same method. These findings offer a promising alternative to the more common supercycle approach and overall, important insights into multicomponent ALD processes.
