Abstract: A method for making an interconnection component includes forming a mask layer that covers a first opening in a sheet-like element that includes a first opening extending between the first and second surfaces of the element. The element consists essentially of a material having a coefficient of thermal expansion of less than 10 parts per million per degree Celsius. The first opening includes a central opening and a plurality of peripheral openings open to the central opening that extends in an axial direction of the central opening. A conductive seed layer can cover an interior surface of the first opening. The method further includes forming a first mask opening in at least a portion of the mask layer overlying the first opening to expose portions of the conductive seed layer within the peripheral openings; and forming electrical conductors on exposed portions of the conductive seed layer.

Abstract: A contact pad includes a solder-wettable porous network (310) which wicks the molten solder (130) and thus restricts the lateral spread of the solder, thus preventing solder bridging between adjacent contact pads.

Abstract: Advanced flat metals for microelectronics are provided. While conventional processes create large damascene features that have a dishing defect that causes failure in bonded devices, example systems and methods described herein create large damascene features that are planar. In an implementation, an annealing process creates large grains or large metallic crystals of copper in large damascene cavities, while a thinner layer of copper over the field of a substrate anneals into smaller grains of copper. The large grains of copper in the damascene cavities resist dishing defects during chemical-mechanical planarization (CMP), resulting in very flat damascene features. In an implementation, layers of resist and layers of a second coating material may be applied in various ways to resist dishing during chemical-mechanical planarization (CMP), resulting in very flat damascene features.

Abstract: Methods and apparatuses for stacking devices in an integrated circuit assembly are provided. A tray for supporting multiple dies of a semiconductor material enables both top side processing and bottom side processing of the dies. The dies can be picked and placed for bonding on a substrate or on die stacks without flipping the dies, thereby avoiding particulate debris from the diced edges of the dies from interfering and contaminating the bonding process. In an implementation, a liftoff apparatus directs a pneumatic flow of gas to lift the dies from the tray for bonding to a substrate, and to previously bonded dies, without flipping the dies. An example system allows processing of both top and bottom surfaces of the dies in a single cycle in preparation for bonding, and then pneumatically lifts the dies up to a target substrate so that top sides of the dies bond to bottom sides of dies of the previous batch, in an efficient and flip-free assembly of die stacks.

Abstract: Representative implementations of devices and techniques provide a hybrid interposer for 3D or 2.5D package arrangements. A quantity of pockets is formed on a surface of a carrier in a predetermined pattern. The pockets are filled with a reflowable conductive material. Chip dice are coupled to the interposer carrier by fixing terminals of the dice into the pockets. The carrier may include topside and backside redistribution layers to provide fanout for the chip dice, for coupling the interposer to another carrier, board, etc. having a pitch greater than that of the chip dice.

Abstract: An interconnection component includes a semiconductor material layer having a first surface and a second surface opposite the first surface and spaced apart in a first direction. At least two metalized vias extend through the semiconductor material layer. A first pair of the at least two metalized vias are spaced apart from each other in a second direction orthogonal to the first direction. A first insulating via in the semiconductor layer extends from the first surface toward the second surface. The insulating via is positioned such that a geometric center of the insulating via is between two planes that are orthogonal to the second direction and that pass through each of the first pair of the at least two metalized vias. A dielectric material at least partially fills the first insulating via or at least partially encloses a void in the insulating via.
