Annealing study of AlN thin films grown on Si(100) and Si(111) substrates via reactive RF Magnetron sputtering
Abstract
For this study, AlN thin films were subjected to annealing and the crystallinity was investigated via XRD experiments. AlN thin films were deposited on Si(100) and Si(111) via RF Magnetron sputtering. The films were subjected to heat treatment at 1000°C for 30 minutes and 1 hour. Results from the XRD plots show that annealing improves the crystallinity of the thin film where the crystal structure of the AlN films have preferred crystal planes depending on the substrate.
