Abstract
PZT crystals are peripherally coated in manufacture by cutting a series of intersecting first kerfs in a wafer comprising a plurality of PZT crystal precursors, filling the kerfs with a coating resin, and cutting a second, narrower kerf in the locus of the first kerfs to separate the crystals while providing them a peripheral coating of the coating resin.
