Abstract
A method for making ultrasound transducers and ultrasound probes includes providing a piezoelectric layer having a first surface and a second surface, where the second surface is on an opposite side of the piezoelectric layer from the first surface. The method includes fabricating a plurality of conductive through vias extending from the first surface to the second surface of the piezoelectric layer, where fabricating the plurality of conductive through vias comprises cutting a plurality of trenches through the piezoelectric layer and filling each of the plurality of trenches with a conductive material. The method includes cutting the piezoelectric layer into a plurality of transducer units after fabricating the plurality of conductive through vias and cutting each of the transducer units into a plurality of transducer elements.
