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 1):
A method, comprising:\n placing a die in a die tray comprising at least one through-hole allowing processing on both a top side and a bottom side of the die; preparing both the top side and the bottom side of the die for direct bonding to a substrate or to another die without flipping the die; direct bonding the top side to a respective substrate or to another die; and direct bonding the bottom side to a respective substrate or to another die.
