    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.

    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.

    Abstract: A stacked integrated circuit (IC) device includes a first die having a first face, a first active region adjacent to the first face, and first die-interconnect contacts disposed on the first face and connected to first circuitry. The stacked IC device includes a second die having a second face, a second active region adjacent to the second face, and second die-interconnect contacts disposed on the second face and connected to second circuitry. The first face is oriented toward the second face, and the first die-interconnect contacts are connected to the second die-interconnect contacts. The stacked IC device includes a set of redistribution layers electrically connected to redistribution contacts on the first face, the second face, or both. The stacked IC device also includes interconnect conductors connected to the redistribution layers to provide signal paths from the first die, the second die, or both, to a set of external contacts.

    Abstract: A device comprising an integrated device. The integrated device comprising a die substrate; an interconnect portion coupled to the die substrate, a plurality of pillar interconnects and a passivation layer coupled to the interconnect portion. The interconnect portion includes a first plurality of pads and a second plurality of pads. The first plurality of pads are configured to provide a first plurality of electrical paths for input/output signals. The second plurality of pads are configured to provide a second plurality of electrical paths for power. The plurality of pillar interconnects are coupled to the first plurality of pads and the second plurality of pads. The passivation layer comprises a plurality of openings. The plurality of openings include at least one opening located over a pad from the first plurality of pads.
