Bonded die structures and methods of fabrication thereof that provide reduced defects and higher reliability. A laser grooving process may be used to precut bonded device structures prior to a final dicing process. The laser grooving process may form relatively deep grooves in the bonded device structure that may extend beyond the bonding interface between a first device structure and a second device structure. A final dicing process along the precut grooves may be used to separate individual bonded die structures. Because the dicing occurs along the deep precut grooves that extend through the bonding interface between the stacked device structures, the dicing blade may not cut through or come into contact with the bonding interface. This may result in in reduced mechanical stress, which may decrease the occurrence of delamination defects between the device structures and thereby provide improved reliability and increased yields.
