    Abstract: A conformal power delivery structure, a three-dimensional (3D) stacked die assembly, a system including the 3D stacked die assembly, and a method of forming the conformal power delivery structure. The power delivery structure includes a package substrate, a die adjacent to and electrically coupled to the package substrate; a first power plane adjacent the upper surface of the package substrate and electrically coupled thereto; a second power plane at least partially within recesses defined by the first power plane and having a lower surface that conforms with the upper surface of the first power plane; and a dielectric material between the first power plane and the second power plane.

    Abstract: A die assembly comprising: a first component layer having conductive through-connections in an insulator, a second component layer comprising a die, and an active device layer (ADL) at an interface between the first component layer and the second component layer. The ADL comprises active elements electrically coupled to the first component layer and the second component layer. The die assembly further comprises a bonding layer electrically coupling the ADL to the second component layer. In some embodiments, the die assembly further comprises another ADL at another interface between the first component layer and a package support opposite to the interface. The first component layer may comprise another die having through-substrate vias (TSVs). The die and the another die may be fabricated using different process nodes.

    Abstract: Disclosed herein are microelectronic assemblies including microelectronic components coupled by direct bonding, and related structures and techniques. In some embodiments, a microelectronic assembly may include a first microelectronic component including a first guard ring extending through at least a portion of a thickness of and along a perimeter; a second microelectronic component including a second guard ring extending through at least a portion of a thickness of and along a perimeter, where the first and second microelectronic components are coupled by direct bonding; and a seal ring formed by coupling the first guard ring to the second guard ring. In some embodiments, a microelectronic assembly may include a microelectronic component coupled to an interposer that includes a first liner material at a first surface; a second liner material at an opposing second surface; and a perimeter wall through the interposer and connected to the first and second liner materials.
