Summary :

Electron cyclotron resonance (ECR) plasma oxidation of AlN thin films was studied to form the AlON high-κ gate insulator. The leakage current was found to be decreased, and also the surface roughness was improved with the ECR plasma oxidation of AlN thin films. The leakage current was further decreased after 1000 RTA in N2 with little increase of equivalent oxide thickness (EOT) because of the high quality interfacial layer formation.
