Abstract
A method of fabricating a transducer includes embedding signal flexes and ground-return flexes inside a backing block. The method includes forming stack configurations with a height in elevation and a width perpendicular to the height. The forming includes: dicing a piezoelectric layer in the elevation into rows (separating the piezoelectric layer into portions); defining a beam pattern for the transducer by aligning the portions on the backing block; and forming gaps in-between each piezoelectric layer portion and each adjacently aligned piezoelectric layer portion. The method includes forming stacks by bonding one or more matching layers to the piezoelectric layer portions by utilizing a conductive surface of a first matching layer of the one or more matching layers. The method also includes forming cavities in the one or more matching layers in elevation, dicing the stacks along an elevation direction into multiple elements, and filling the cavities with a material.
