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 13):
The method of  claim 11 , further comprising:\n placing the dies in the die tray comprising through-holes allowing processing on both a top side and a bottom side of each die; preparing both the top sides of the dies and the bottom sides of the dies for bonding to a surface of the substrate or to other dies already bonded to the substrate; pneumatically lifting the dies from the die tray and without flipping the dies bonding the top sides of the dies to the surface of the substrate or to the other dies already bonded to the substrate; and repeating the method multiple times to bond top sides of each next batch of the dies to each previous batch of the dies already bonded to the substrate to make respective stacks of the dies.
