Abstract
Abstract A electronic device having a structure in which at least one electronic element, including an insulating film or covered with a protecting film, is formed on a substrate, where the insulating or protecting film consist principally of aluminum nitride. Alternatively, the insulating or protecting film can be a laminated member composed of a film consisting principally of aluminum nitride and a film consisting principally of silicon oxide or silicon nitride.
