摘要： 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.

摘要： Bonding pedestals on substrates, and their manufacture, for direct bonding integrated circuit (IC) dies onto substrates. The electrical interconnections of one or more IC dies and a substrate are bonded together with the IC dies on and overhanging the pedestals. A bonding pedestal may be formed by etching down the substrate around the interconnections. A system may include one or more such pedestals above and adjacent a recessed surface on a substrate with IC dies overhanging the pedestals. Such a system may be coupled to a host component, such as a board, and a power supply via the host component.

摘要： An integrated circuit (IC) device comprises a host component and an IC die directly bonded to the host component. The IC die comprises a substrate material layer and a die metallization level between the substrate material layer and host component. The IC die includes an upper die alignment fiducial between the die metallization level and host component. The upper die alignment fiducial at least partially overlaps one or more metallization features within the die metallization level. In embodiments, at least two orthogonal edges of the upper die alignment fiducial do not overlap any of the metallization features within the die metallization level. In embodiments, the IC die includes a lower die alignment fiducial between the substrate material layer and the die metallization level. The lower die alignment fiducial may at least partially overlap one or more second metallization features within a second die metallization level of the IC die.
