    Abstract: Techniques are disclosed for heteroepitaxial growth of a layer of lattice-mismatched semiconductor material on an initial substrate, and transfer of a defect-free portion of that layer to a handle wafer or other suitable substrate for integration. In accordance with some embodiments, transfer may result in the presence of island-like oxide structures on the handle wafer/substrate, each having a defect-free island of the lattice-mismatched semiconductor material embedded within its upper surface. Each defect-free semiconductor island may have one or more crystalline faceted edges and, with its accompanying oxide structure, may provide a planar surface for integration. In some cases, a layer of a second, different semiconductor material may be heteroepitaxially grown over the handle wafer/substrate to fill areas around the transferred islands. In some other cases, the handle wafer/substrate itself may be homoepitaxially grown to fill areas around the transferred islands.

    Abstract: Hybrid bonded multi-level die stacks, related apparatuses, systems, and methods of fabrication are disclosed. First-level integrated circuit (IC) dies and a base substrate each include hybrid bonding regions surrounded by hydrophobic structures. The hybrid bonding regions are brought together with a liquid droplet therebetween, and capillary forces cause the IC die to self-align. A hybrid bond is formed by evaporating the droplet followed by anneal. Hybrid bonding regions of second-level IC dies are similarly bonded to hybrid bonding regions on backsides of the first-level IC dies. This is repeated for any number of subsequent levels of IC dies. IC structures including the bonded IC dies and portions of the base substrate are segmented and assembled.
