Abstract: Semiconductor packages having a sealant bridge between an integrated heat spreader and a package substrate are described. In an embodiment, a semiconductor package includes a sealant bridge anchoring the integrated heat spreader to the package substrate at locations within an overhang gap laterally between a semiconductor die and a sidewall of the integrated heat spreader. The sealant bridge extends between a top wall of the integrated heat spreader and a die side component, such as a functional electronic component or a non-functional component, or a satellite chip on the package substrate. The sealant bridge modulates warpage or stress in thermal interface material joints to reduce thermal degradation of the semiconductor package.

Abstract: Methods of forming microelectronic package structures/modules, and structures formed thereby, are described. Structures formed herein may include a first die disposed on a substrate and a second die disposed adjacent the first die on the substrate. A cooling solution is attached to the substrate, wherein a rib extends from a central region of the cooling solution and is attached to the substrate. The rib is disposed between the first die and the second die.
