This study aims at investigating the influence of gas atmospheres on the dewetting properties of DC sputtered and rapid thermally annealed silver (Ag) nanofilms. The annealing temperature ranged from 400℃ to 600℃ and the gases studied were argon (Ar) and nitrogen (N2). Scanning electron microscope (SEM) and focused ion beam (FIB) were employed for morphological studies, while the X-ray diffraction (XRD) technique was applied in the structural analysis of the films. The SEM and top-view FIB-SEM images of Ag films annealed in both atmospheres were characterized by irregular shaped holes. At fixed temperature, the films annealed in the N2 atmospheres gave higher hole density and larger hole sizes than the film annealed in the Ar atmosphere. Additionally, the hole density decreased with the annealing time. For films annealed in the N2 atmosphere, isolated dewetted particles were only obtained at 600℃ substrate temperature. The XRD patterns of all the films were characterized by Ag metallic peaks. No significant difference was observed among the films’ crystal structures. The annealing atmospheres mainly influences the morphologies of Ag nanofilms.
