Abstract
A method for forming an acoustical stack for an ultrasound probe comprises partly dicing a single crystal piezoelectric material to form single crystal pieces that are partly separated by a plurality of kerfs. The single crystal piezoelectric material comprises a carrier layer. The kerfs are filled with a kerf filling material to form a single crystal composite and the carrier layer is removed. At least one matching layer is attached to the single crystal composite, and dicing within the kerfs is accomplished to form separate acoustical stacks from the single crystal composite.
