Publication number: 20240063142Abstract: 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.Type: ApplicationFiled: August 19, 2022Publication date: February 22, 2024Applicant: Intel CorporationInventors: Adel Elsherbini, Wenhao Li, Bhaskar Jyoti Krishnatreya, Tushar Talukdar, Botao Zhang, Yi Shi, Haris Khan Niazi, Feras Eid, Nagatoshi Tsunoda, Xavier Brun, Mohammad Enamul Kabir, Omkar Karhade, Shawna Liff, Jiraporn Seangatith
