    Abstract: Disclosed is a semiconductor device. In an aspect, a semiconductor device includes: a first-tier passive device including a substrate portion, a passive device portion, and a metallization portion disposed in a stacked configuration; and one or more second-tier passive devices disposed over the first-tier passive device. Each one of the one or more second-tier passive devices includes: a substrate portion, a passive device portion, and a metallization portion disposed in a stacked configuration; and a set of through substrate vias (TSVs) passing through a corresponding substrate portion and electrically coupled to a corresponding metallization portion. The semiconductor device comprises a passive component including the passive device portion of the first-tier passive device electrically coupled to one or more passive device portions of the one or more second-tier passive devices through the metallization portions of the first-tier passive device and the one or more second-tier passive devices.

    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.

    Abstract: Disclosed are techniques for integrated circuit device. In an aspect, an integrated circuit device includes a metallization structure that includes a top metal layer structure; a passivation layer on the metallization structure; a bump structure disposed on the first bump line structure; and a first polymer protection layer. The passivation layer may include one or more first openings. The first bump line structure may include one or more first extended portions respectively extending toward the top metal layer structure through the one or more first openings. The bump structure may be electrically coupled to the first bump line structure. The first polymer protection layer may be on the passivation layer, on a portion of the first bump line structure, and in contact with a side surface of the first bump line structure.

    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.
