    摘要: Provided is a composite wafer having an oxide single-crystal film transferred onto a support wafer, the film being a lithium tantalate or lithium niobate film, and the composite wafer being unlikely to have cracking or peeling caused in the lamination interface between the film and the support wafer. More specifically, provided is a method of producing the composite wafer, including steps of: implanting hydrogen atom ions or molecule ions from a surface of the oxide wafer to form an ion-implanted layer inside thereof; subjecting at least one of the surface of the oxide wafer and a surface of the support wafer to surface activation treatment; bonding the surfaces together to obtain a laminate; heat-treating the laminate at 90°C or higher at which cracking is not caused; and applying ultrasonic vibration to the heat-treated laminate to split along the ion-implanted layer to obtain the composite wafer.

    摘要: A method and an apparatus for smoothing surfaces on an atomic scale. The invention performs smoothing of surfaces by use of a low energy ion or neutral noble gas beam, which may be formed in an ion source or a remote plasma source. The smoothing process may comprise a post-deposition atomic smoothing step (e.g., an assist smoothing step) in a multilayer fabrication procedure. The invention utilizes combinations of relatively low particle energy (e.g., below the sputter threshold of the material) and near normal incidence angles, which achieve improved smoothing of a surface on an atomic scale with substantially no etching of the surface.
