Abstract: The present technology is directed to manufacturing collars for under-bump metal (UBM) structures for die-to-die and/or package-to-package interconnects and associated systems. A semiconductor die includes a semiconductor material having solid-state components and an interconnect extending at least partially through the semiconductor material. An under-bump metal (UBM) structure is formed over the semiconductor material and is electrically coupled to corresponding interconnects. A collar surrounds at least a portion of the side surface of the UBM structure, and a solder material is disposed over the top surface of the UBM structure.

Abstract: An apparatus relating generally to a substrate is disclosed. In this apparatus, a first metal layer is on the substrate. The first metal layer has an opening. The opening of the first metal layer has a bottom and one or more sides extending from the bottom. A second metal layer is on the first metal layer. The first metal layer and the second metal layer provide a bowl-shaped structure. An inner surface of the bowl-shaped structure is defined responsive to the opening of the first metal layer and the second metal layer thereon. The opening of the bowl-shaped structure is configured to receive and at least partially retain a bonding material during a reflow process.
