PATTERNED INORGANIC FILM, PIEZOELECTRIC DEVICE, AND PROCESS FOR PRODUCING THE SAME |
摘要 |
An inorganic film formed of an inorganic material on a metal film having a surface including surface-oxidized areas. The surface-oxidized areas are surface oxidized to different degrees. For example, the surface-oxidized areas are one or more lowly-surface-oxidized areas and one or more highly-surface-oxidized areas. The inorganic film includes regions which are respectively formed on the surface-oxidized areas, and the regions have different crystal structures according to the different degrees of surface oxidation. For example, a patterned inorganic film constituted by one or more protruding portions arranged on one or more lowly-surface-oxidized areas of the surface of the metal film can be produced by removing the portions of the inorganic film formed on highly-surface-oxidized areas.
