Abstract
Etched trenches in a bond material for die singulation, and associated systems and methods are disclosed. A method for solid state transducer device singulation in accordance with one embodiment includes forming a plurality of trenches by etching through a metallic bond material forming a bond between a carrier substrate and a plurality of the dies and singulating the carrier substrate along the trenches to separate the dies. In particular embodiments, the trenches extend into the carrier substrate. In further particular embodiments, the dies are at least partially, encapsulated in a dielectric material.
