Disclosed herein are integrated circuit (IC) packages, and related structures and techniques. In some embodiments, an IC package may include: a die; a redistribution structure, wherein the die is coupled to the redistribution structure via first-level interconnects and solder; a solder resist; and second-level interconnects coupled to the redistribution structure through openings in the solder resist.

In described examples, a method (400) includes applying a die attach material to a die pad of an integrated circuit (410). The die attach material is employed as a bonding material to the die pad. The method (400) includes mounting an integrated circuit die to the die pad of the integrated circuit via the die attach material (420). The method (400) includes printing an adhesion deposition material on the die attach material appearing at the interface of the integrated circuit die and the die pad of the integrated circuit to mitigate delamination between the integrated circuit die and the die pad (430).

A bonding element includes a first transient liquid phase (TLP) bonding element including a first material and a second material, the first material having a higher melting point than the second material, a ratio of a quantity of the first material and the second material in the first TLP bonding element having a first value and a second TLP bonding element including the first material and the second material, a ratio of a quantity of the first material and the second material in the second TLP bonding element having a second value different from the first value.

Embedded air core inductors are described for integrated circuit package substrates. The substrates have a thermal conductor for the inductors. One example includes a package substrate to carry an integrated circuit die, the package substrate having a plurality of top side pads to connect to the die on a top side and a plurality of bottom side pads to connect to an external component on a bottom side. An inductor is embedded within the package substrate, a thermal conductor is embedded within the package substrate adjacent to the inductor to conduct heat away from the inductor, and a heat sink is thermally coupled to the thermal conductor to receive the heat from the conductor.

Wirebond bondpads on semiconductor packages that result in reduced cross-talk and/or interference between vertical wires are disclosed. The vertical wirebonds may be disposed in the semiconductor package with stacked dies, where the wires are substantially normal to the bondpads to which the vertical wirebonds are attached on the dies. The wirebond pads may include signal pads that carry input/output (I/O) to/from the die package, as well as ground bondpads. The vertical wirebond bondpads may have widths that are greater than the space between adjacent bondpads. Bondpads may be fabricated to be larger than the size requirements for reliable wirebond formation on the bondpads. For a fixed pitch bondpad configuration, the size of the signal bondpads adjacent to the ground bondpads may be greater than half of the pitch. By increasing the size (e.g., width) of the signal bondpads adjacent to a ground line relative to the space therebetween, improved cross-talk performance may be achieved.

An automotive electronic device includes a pocket, which houses electronic components, bond wires connecting the electronic components, and a protective gel to encapsulate the electronic components and bond wires. A pocket cover has fins that protrude into the gel to reduce vibration of the gel and reduce vibration fatigue failure of the bond wires. The fins may: divide the gel into a plurality of cells; reduce the width of cells perpendicular to the bond wires; protrude deeper into the gel than the bond wires; and/or have differing shapes and/or depths.

Bonded surfaces are formed by adhering first nanorods and second nanorods to respective first and second surfaces. The first shell is formed on the first nanorods and the second shell is formed on the second nanorods, wherein at least one of the first nanorods and second nanorods, and the first shell and the second shell are formed of distinct metals. The surfaces are then exposed to at least one condition that causes the distinct metals to form an alloy, such as eutectic alloy having a melting point below the temperature at which the alloy is formed, thereby bonding the surfaces upon solidification of the alloy.
