Abstract
Silicon nitride () and silicon dioxide () films were prepared by ion-assisted deposition, and a higher deposition rate was achieved for both films. The results of x-ray diffraction and transmission electron microscopy measurements showed that the films have amorphous structures. As measured by infrared (IR) spectrometry and x-ray photoelectron spectrometry, both stoichiometric films have extremely low hydrogen content. The IR optical constants of the films were determined by spectroscopic ellipsometry. Both films exhibited a low extinction coefficient at wavelengths from 2 to . The application of and films on the IR interference coating is demonstrated.
