Stacked die assemblies having a moisture sealant layer according to embodiments are described herein. A microelectronic package structure having a first die with a second and an adjacent third die on the first die. Each of the second and third die comprise hybrid bonding interfaces with the first die. A first layer is on a region of the first die adjacent sidewalls of the second and the third dies, and adjacent an edge portion of the first die. The first layer comprises a diffusion barrier material A second layer is over the first layer, the second layer, wherein a top surface of the second layer is substantially coplanar with the top surfaces of the second and third dies. The first layer provides a hermetic moisture sealant layer for stacked die package structures.

Moisture seal coating of hybrid bonded stacked die package assembly

Embodiments described herein may be related to apparatuses, processes, and techniques for a barrier that surrounds one or more dies which are electrically coupled with one or more electrical connections on a wafer. The barrier may be a hermetic barrier that is formed on a wafer prior to singulation to prevent moisture intrusion from a side of the wafer that may compromise the one or more electrical connections. Other embodiments may be described and/or claimed.

Hermetic barrier surrounding a plurality of dies

Compute complexes, base dies, and methods related to leveraging reticle stitching for improved device interconnects are discussed. A base die includes first and second regions having device layers, lower level metallization layers, and through vias fabricated using the same reticles. In the first region, a first subset of the through vias are contacted by higher metallization layers and, in the second region, a second distinct subset of the through vias are contacted by higher metallization layers such that the first and second metallization layers provide unique routing through vias having shared layouts and relative locations in the first and second regions.

Simulating die rotation to minimize area overhead of reticle stitching for stacked dies

Stitched dies having a cooling structure are described. For example, an integrated circuit structure includes a first die including a first device layer and a first plurality of metallization layers over the first device layer. The integrated circuit structure also includes a second die including a second device layer and a second plurality of metallization layers over the second device layer, the second die separated from the second die by a scribe region. A common conductive interconnection is coupling the first die and the second die at a first side of the first and second dies. A plurality of microfluidic channels is coupled to the first side of the first and second dies.

Cooling approaches for stitched dies

An integrated circuit (IC) die comprises a first metallization layer comprising first interconnect structures which each extend through the first metallization layer, a second metallization layer comprising second interconnect structures which each extend through the second metallization layer, an interlayer dielectric (ILD) stack between the first metallization layer and the second metallization layer. The ILD stack comprises a stress modulation layer on the first metallization layer and a capping layer on the stress modulation layer. A first intrinsic stress in a first material of the stress modulation layer is to mitigate a second intrinsic stress in the first metallization layer.
