Cold fluid semiconductor device release during pick and place operations, and associated systems and methods
Systems and methods for releasing semiconductor dies during pick and place operations are disclosed. In one embodiment, a system for handling semiconductor dies comprises a support member positioned to carry at least one semiconductor die releasably attached to a support substrate. The system further includes a picking device having a pick head coupleable to a vacuum source and positioned to releasably attach to the semiconductor die at a pick station. The system still further includes a cooling member coupleable to a cold fluid source and configured to direct a cold fluid supplied by the cold fluid source toward the support substrate at the pick station. The cold fluid cools a die attach region of the substrate where the semiconductor die is attached to the substrate to facilitate removal of the semiconductor die.
METHOD OF SINGULATING SEMICONDUCTOR WAFER HAVING A PLURALITY OF DIE AND A BACK LAYER DISPOSED ALONG A MAJOR SURFACE
Die are singulated from a wafer having a back layer by placing the wafer onto a first carrier substrate with the back layer adjacent the carrier substrate, forming singulation lines through the wafer to expose the back layer within the singulation lines, and using a plate structure to apply a pressure to the wafer to separate the back layer in the singulation lines. The pressure can be applied through the first carrier substrate proximate to the back layer, or can be applied through a second carrier substrate attached to a front side of the wafer opposite to the back layer.

Method of singulating semiconductor wafer having back layer
In one embodiment, die are singulated from a wafer having a back layer by placing the wafer onto a first carrier substrate with the back layer adjacent the carrier substrate, forming singulation lines through the wafer to expose the back layer within the singulation lines, and using a mechanical device to apply localized pressure to the wafer to separate the back layer in the singulation lines. The localized pressure can be applied through the first carrier substrate proximate to the back layer, or can be applied through a second carrier substrate attached to a front side of the wafer opposite to the back layer.
