Abstract:
The embodiments described provide methods and structures for forming support structures between dies and substrate(s) of a three dimensional integrated circuit (3DIC) structures. Each support structure adheres to surfaces of two neighboring dies or die and substrate to relieve stress caused by bowing of the die(s) and/or substrate on the bonding structures formed between the dies or die and substrate. The cost of the support structures is much lower than other processes, such as thermal compression bonding, to reduce the effect of bowing of dies and substrates on 3DIC formation. The support structures improves yield of 3DIC structures.
