POLARIZATION INVERSION FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a polarization inversion forming method that can homogeneously generate a polarization inversion state in a polarization inversion area even when a region where polarization inversion is formed has a large area of≥50μm in width and reduce the intensity of a voltage applied during the polarization inversion.

SOLUTION: The polarization inversion forming method of inverting the polarization of a desired region of a ferroelectric substrate 1 is characterized in that the polarization of the desired region 20 on a surface of the ferroelectric substrate is inverted by performing nucleus growth by jetting fine hard materials to the substrate surface, giving an impact with a strike member having a fine tip diameter, or rubbing fine hard materials scattered and arranged on the substrate surface, and then applying a specified voltage to the desired region.
