  • Publication number: 20220270995
    Abstract: Disclosed are examples of integrated circuit (IC) structures and techniques to fabricate IC structures. Each IC package may include a die (e.g., a flip-chip (FC) die) and one or more die interconnects to electrically couple the die to a substrate. The die interconnect may include a pillar, a wetting barrier on the pillar, and a solder cap on the wetting barrier. The wetting barrier may be wider than the pillar such that during solder reflow, solder wetting of sidewall of the pillar is minimized or prevented all together. The die interconnect may also include a low wetting layer formed on the wetting barrier, which can further mitigate solder wetting problems.

  • Publication number: 20210407939
    Abstract: Disclosed is a flip-chip device. The flip-chip device includes a die having a plurality of under bump metallizations (UBMs); and a package substrate having a plurality of bond pads. The plurality of UBMs include a first set of UBMs having a first size and a first minimum pitch and a second set of UBMs having a second size and a second minimum pitch. The first set of UBMs and the second set of UBMs are each electrically coupled to the package substrate by a bond-on-pad connection.

  • Publication number: 20210210449
    Abstract: A thermal compression flip chip (TCFC) bump may be used for high performance products that benefit from a fine pitch. In one example, a new TCFC bump structure adds a metal pad underneath the TCFC copper pillar bump to cover the exposed aluminum bump pad. This new structure prevents the pad from corroding and reduces mechanical stress to the pad and underlying silicon dielectric layers enabling better quality and reliability and further bump size reduction. For example, a flip chip connection may include a substrate; a metal pad on a contact side of the substrate and a first passivation layer on the contact side of the substrate to protect the metal pad from corrosion.

  • Publication number: 20180331061
    Abstract: A device comprising a semiconductor die and a redistribution portion coupled to the semiconductor die. The redistribution portion includes a passivation layer and a redistribution interconnect comprising a first surface and a second surface opposite to the first surface. The redistribution interconnect is formed over the passivation layer such that the first surface is over the passivation layer and the second surface is free of contact with any passivation layer. The device includes a bump interconnect coupled to the second surface of the redistribution interconnect. In some implementations, the bump interconnect comprises a surface that faces the redistribution interconnect, and wherein an entire surface of the bump interconnect that faces the redistribution interconnect is free of contact with the passivation layer.
