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. It significantly suppresses a situation of dissolution of the piezoelectric film 52A and realizes improvement in characteristics of the piezoelectric device 74 made.

摘要:
Provided is a thin-film piezoelectric element which reduces the influence of an oxide film left on the electrode film on the degradation of element characteristics, and a method of making the thin-film piezoelectric element. The thin-film piezoelectric element has ZrO2 as the main component of the outermost layer of the oxide film which covers the laminate. Young's modulus of the ZrO2 is 190 GPa, giving a significantly low value compared with Young's modulus of MgO, 245 GPa. Consequently, the influence of the oxide film on the reduction in the displacement magnitude of the piezoelectric film is smaller than the influence of the MgO thin film left in the conventional thin-film piezoelectric element. As a result, the thin-film piezoelectric element decreases the influence of the oxide film on the degradation of element characteristics compared with the conventional thin-film piezoelectric element.

摘要:
An improved process for producing a laminated resin foam composed of two resin foam layers of different characteristic properties wherein the layers are integrally bonded together. A first foamable resin liquid for forming flexible foam is poured into a first space in a foam processing mold on one side of a barrier projecting from the wall of the mold and pouring a second foamable resin liquid for forming a foam less flexible than the first flexible foam into a second space in said foam processing mold on the other side of said barrier. The two foamable resin liquids foam beyond the barrier into contact with each other to form the two laminated foam layers. One improvement in the process includes wetting a substantial portion of the mold cavity with the first foamable resin liquid. Various shapes of molds and barriers will produce different shapes and characteristics of the resultant foam pad, such as for a car seat.
