  • Ferroelectric ceramics and method for manufacturing the same
    Patent number: 10115887
    Abstract: An aspect of the present invention relates to ferroelectric ceramics including a stacked film formed on a Si substrate, a Pt film formed on the stacked film, a SrTiO3 film formed on the Pt film, and a PZT film formed on the SrTiO3, wherein the stacked film is formed by repeating sequentially N times a first ZrO2 film and a Y2O3 film, and a second ZrO2 film is formed on the film formed repeatedly N times, the N being an integer of 1 or more. It is preferable that a ratio of Y/(Zr+Y) of the stacked film is 30% or less.
    Type: Grant
    Filed: November 17, 2014
    Date of Patent: October 30, 2018
    Assignee: ADVANCED MATERIAL TECHNOLOGIES, INC.

  • Piezoelectric film, ferroelectric ceramics and inspection method of piezoelectric film
    Patent number: 9773968
    Abstract: To obtain a piezoelectric film having excellent piezoelectric properties. An aspect of the present invention is a piezoelectric film having a crystal oriented in the c-axis direction and a crystal oriented in the a-axis direction, in which, when denoting the amount of a (004) component of the crystal oriented in the c-axis direction by C and denoting the amount of a (400) component of the crystal oriented in the a-axis direction by A, the piezoelectric film satisfies a formula 1 below. C/(A+C)?0.
