  • Patent number: 10411181
    Abstract: Devices and methods described herein provide electrode pair access from a single side of a device by using one or more via holes through the device. The via hole can pass through or near the center of the device. By creating a conductive path through the via hole of the device, devices and methods of the present disclosure advantageously provide access to a pair of electrodes, each of which contacts a different side of a device layer, on a single side of the device while enabling a greater active device area than is possible using conventional techniques. In addition, the central location of the via hole provides favorable mechanical properties by avoiding radial constriction of the device layers in applications such as piezoelectric devices.
