    Abstract: An integrated circuit assembly may be fabricated to include an integrated circuit device having a backside surface and a backside metallization layer on the backside surface of the integrated circuit device, wherein the backside metallization layer comprises a bond layer on the backside surface of the integrated circuit device, a high thermal conductivity layer on the bond layer, and a cap layer on the high thermal conductivity layer. The bond layer may be a layered stack comprising an adhesion promotion layer on the backside of the integrated circuit device and at one least metal layer. The high thermal conductivity layer may be an additively deposited material having a thermal conductivity greater than silicon, such as copper, silver, aluminum, diamond, silicon carbide, boron nitride, aluminum nitride, and combinations thereof.

    Abstract: A porous mesh structure for use in the thermal management of integrated circuit devices may be formed as a solid matrix with a plurality of pores dispersed therein, wherein the solid matrix may be a plurality of fused matrix material particles and the plurality of pores may comprise between about 10% and 90% of a volume of the porous mesh structure. The porous mesh structure may be formed on an integrated circuit device and/or on a heat dissipation assembly component, and may be incorporated into an immersion cooling assembly, wherein the porous mesh structure may act as a nucleation site for a working fluid in the immersion cooling assembly.

    Abstract: An integrated circuit package may be fabricated with a universal dummy device, instead of utilizing a dummy device that matches the bump layer of an electronic substrate of the integrated circuit package. In one embodiment, the universal dummy device may comprise a device substrate having an attachment surface and a metallization layer on the attachment surface, wherein the metallization layer is utilized to form a connection with the electronic substrate of the integrated circuit package. In a specific embodiment, the metallization layer may be a single structure extending across the entire attachment surface. In another embodiment, the metallization layer may be patterned to enable gap control between the universal dummy device and the electronic substrate.
