Claim Text:
1. A method comprising: obtaining a structure comprising a device wafer including a device side comprising a plurality of integrated circuits, a UV-transmissive handler, and a bonding layer that bonds the UV-transmissive handler to the device wafer; applying a resist layer to the device side of the device wafer; patterning the resist layer; singulating the device wafer using deep reactive ion etching, thereby forming a plurality of dies separated by trenches extending completely through the device wafer; removing the patterned resist layer; providing a die pack including a plurality of die cavities and aligning the dies with the die cavities; subjecting at least part of the bonding layer to UV radiation through the UV-transmissive handler, thereby releasing fluence of selected energy in a spot within the bonding layer, the spot having dimensions corresponding to dimensions of the dies, thereby causing release of an individual one of the dies from the UV-transmissive handler into one of the die cavities.
