A microelectronics package comprises a substrate comprising at least two conductive layers that are separated by a first dielectric. At least one island comprising a magnetic material is embedded within the dielectric between the two conductive layers. An inductor structure extends within a via in the at least one island. The via extends between the two conductive layers. The inductor structure comprises a conductive wall along a sidewall of the via, and wherein the conductive wall surrounds a second dielectric and is electrically coupled to the two conductive layers.

Magnetic core inductors on package substrates

An apparatus is provided which comprises: a substrate, a die site on the substrate to couple with a die, a die side component site on the substrate to couple with a die side component, and a raised barrier on the substrate between the die and die side component sites to contain underfill material disposed at the die site, wherein the raised barrier comprises electroplated metal. Other embodiments are also disclosed and claimed.

Package with underfill containment barrier

Embodiments disclosed herein include electronic packages and methods of making electronic packages. In an embodiment, the electronic package comprises a package substrate, an array of first level interconnect (FLI) bumps on the package substrate, wherein each FLI bump comprises a surface finish, a first pad on the package substrate, wherein the first pad comprises the surface finish, and wherein a first FLI bump of the array of FLI bumps is electrically coupled to the first pad, and a second pad on the package substrate, wherein the second pad is electrically coupled to the first pad.

Sacrificial pads to prevent galvanic corrosion of FLI bumps in EMIB packages

A device and method for providing enhanced bridge structures is disclosed. A set of conducting and insulating layers are deposited and lithographically processed. The conducting layers have uFLS routing. A bridge with uFLS contacts and die disposed on the underlying structure such that the die are connected with the uFLS contacts and uFLS routing. For core-based structures, the layers are formed after the bridge is placed on the underlying structure and the die connected to the bridge through intervening conductive layers. For coreless structures, the layers are formed over the bridge and carrier, which is removed prior to bonding the die to the bridge, and the die bonded directly to the bridge.

Device and method of very high density routing used with embedded multi-die interconnect bridge

Embodiments that allow multi-chip interconnect using organic bridges are described. In some embodiments an organic package substrate has an embedded organic bridge.
