Abstract
A method for fabricating a piezoelectric multilayer are described. The method includes providing conductive layers. Alternating conductive layers are electrically connected. A first plurality of alternating conductive layers is electrically isolated from a second plurality of alternating conductive layers. Piezoelectric layers are interleaved with the conductive layers. Apertures are provided in the piezoelectric layers. A first conductive plug electrically connects the first plurality of alternating conductive layers, includes a first plurality of segments, and is in apertures in the piezoelectric layers. Each of the first plurality of segments extends through one of the piezoelectric layers. A second conductive plug electrically connects the second plurality of alternating conductive layers, includes a second plurality of segments, and is in a second portion of the plurality of apertures. Each of the second plurality of segments extends through one of the plurality of piezoelectric layers.
