  • Patent number: 8183749
    Abstract: The present invention provides an electronic device with improved characteristics and a method of making the electronic device. In a method of making an electronic device (piezoelectric device) 74 according to the present invention, an outer edge R1 of a piezoelectric film 52A formed on an electrode film 46A of a laminate 60 is located inside an outer edge R2 of the electrode film 46A. For this reason, in removal of a monocrystalline Si substrate 14 from a multilayer board 61, where an etching solution permeates between polyimide 72 and laminate 60, the etching solution circumvents the electrode film 46A before it reaches the piezoelectric film 52A. Namely, a route A of the etching solution to the piezoelectric film 52A is significantly extended by the electrode film 46A. In the method of making the electronic device 74, therefore, the etching solution is less likely to reach the piezoelectric film 52A.

  • Patent number: 8148878
    Abstract: A piezoelectric element having a crystal structure that enables a piezoelectric film to be formed in an unstressed state is provided. The piezoelectric film contains an a-axis oriented crystal and a c-axis oriented crystal, where a difference in lattice constant between the a-axis oriented crystal and the c-axis oriented crystal is not more than 0.06 ?. The present inventors have newly found that a stress accumulated in the piezoelectric film can be reduced while maintaining favorable piezoelectric properties when a condition that the difference in lattice constant between the a-axis oriented crystal and the c-axis oriented crystal is not more than 0.06 ? is satisfied. When the condition is satisfied, the c-axis oriented crystal and the a-axis oriented crystal are properly balanced and as a result crystal particles of the piezoelectric film are closest-packed on its base in an ideal state, which contributes to a reduced stress.
