Methods and apparatus to reduce defects in interconnects between semiconductor dies and package substrates are disclosed. An apparatus includes a substrate and a semiconductor die mounted to the substrate. The apparatus further includes bumps to electrically couple the die to the substrate. Ones of the bumps have corresponding bases. The bases have a shape that is non-circular.

Methods and apparatus to reduce defects in interconnects between semiconductor dies and package substrates

Processes and structures resulting therefrom for the improvement of high speed signaling integrity in electronic substrates of integrated circuit packages, which is achieved with the formation of airgap structures within dielectric material(s) between adjacent conductive routes that transmit/receive electrical signals, wherein the airgap structures decrease the capacitance and/or decrease the insertion losses in the dielectric material used to form the electronic substrates.

Airgap structures for high speed signal integrity

A package substrate and package assembly including a package substrate including a substrate body including electrical routing features therein and a surface layer and a plurality of first and second contact points on the surface layer including a first pitch and a second pitch, respectively, wherein the plurality of first contact points and the plurality of second contact points are continuous posts to the respective ones of the electrical routing features. A method including forming first conductive vias in a package assembly, wherein the first conductive vias include substrate conductive vias to electrical routing features in a package substrate and bridge conductive vias to bridge surface routing features of a bridge substrate; forming a first surface layer and a second surface layer on the package substrate; and forming second conductive vias through each of the first surface layer and the second surface layer to the bridge conductive vias.

An integrated circuit (IC) package substrate, comprising a metallization level within a dielectric material. The metallization level comprises a plurality of conductive features, each having a top surface and a sidewall surface. The top surface of a first conductive feature of the plurality of conductive features has a first average surface roughness, and the sidewall surface of a second conductive feature of the plurality of conductive features has a second average surface roughness that is less than the first average surface roughness.

Embodiments disclosed herein include electronic packages. In an embodiment, an electronic package comprises a package substrate and a bridge substrate embedded in the package substrate. In an embodiment, first pads are over the package substrate, where the first pads have a first pitch, and second pads are over the bridge substrate, where the second pads have a second pitch that is smaller than the first pitch. In an embodiment, a barrier layer is over individual ones of the second pads. In an embodiment, reflown solder is over individual ones of the first pads and over individual ones of the second pads. In an embodiment, a first standoff height of the reflown solder over the first pads is equal to a second standoff height of the reflown solder over the second pads.

Conductive structures in a microelectronic package and having a surface roughness of 50 nm or less are described. This surface roughness is from 2 to 4 times less than can be found in packages with conductive structures (e.g., traces) formed using alternative techniques. This reduced surface roughness has a number of benefits, which in some cases includes a reduction of insertion loss and improves a signal to noise ratio for high frequency computing applications. The reduced surface roughness can be accomplished by protecting the conductive structure r during etch processes and applying an adhesion promoting layer to the conductive structure.

A die assembly is disclosed. The die assembly includes a die, one or more die pads on a first surface of the die and a die attach film on the die where the die attach film includes one or more openings that expose the one or more die pads and that extend to one or more edges of the die.

Patternable die attach materials and processes for patterning

Techniques for fabricating a package substrate comprising a via, a conductive line, and a pad are described. The package substrate can be included in a semiconductor package. For one technique, a package substrate includes: a pad in a dielectric layer; a via; and a conductive line. The via and the conductive line can be part of a structure. Alternatively, the conductive line can be adjacent to the via. The dielectric layer can include a pocket above the pad. One or more portions of the via may be formed in the pocket above the pad. Zero or more portions of the via can be formed on the dielectric layer outside the pocket. In some scenarios, no pad is above the via. The package substrate provides several advantages. One exemplary advantage is that the package substrate can assist with increasing an input/output density per millimeter per layer (IO/mm/layer) of the package substrate.
