Abstract: Multi-die packages including IC die crack mitigation features. Prior to the bonding of IC dies to a host substrate, the IC dies may be shaped, for example with a corner radius or chamfer. After bonding the shaped IC dies, a fill comprising at least one inorganic material may be deposited over the IC dies, for example to backfill a space between adjacent IC dies. With the benefit of a greater IC die sidewall slope and/or smoother surface topology associated with the shaping process, occurrences of stress cracking within the fill and concomitant damage to the IC dies may be reduced. Prior to depositing a fill, a barrier layer may be deposited over the IC die to prevent cracks that might form in the fill material from propagating into the IC die.
