Abstract:
Methods and apparatuses for stacking devices in an integrated circuit assembly are provided. A tray for supporting multiple dies of a semiconductor material enables both top side processing and bottom side processing of the dies. The dies can be picked and placed for bonding on a substrate or on die stacks without flipping the dies, thereby avoiding particulate debris from the diced edges of the dies from interfering and contaminating the bonding process. In an implementation, a liftoff apparatus directs a pneumatic flow of gas to lift the dies from the tray for bonding to a substrate, and to previously bonded dies, without flipping the dies. An example system allows processing of both top and bottom surfaces of the dies in a single cycle in preparation for bonding, and then pneumatically lifts the dies up to a target substrate so that top sides of the dies bond to bottom sides of dies of the previous batch, in an efficient and flip-free assembly of die stacks.

Claim (Index 20):
The apparatus of  claim 19 , wherein each die tray of the multiple instances of the die tray secures multiple dies to simultaneously make multiple stacks of multiple direct bonded dies in simultaneous direct bonding fabrication operations of the respective top sides and respective bottom sides of the multiple direct bonded dies of each stack.
