    Abstract: A bonded structure with protective semiconductor elements including a semiconductor element with active circuitry and a protective element including an obstructive layer and/or a protective circuitry layer. The obstructive layer is configured to inhibit external access to at least a portion of the active circuitry. The protective circuitry layer is configured to detect or disrupt external access to the protective element and/or the active circuitry of the semiconductor element. The semiconductor element and the protective element are directly bonded without an adhesive along a bonding interface.

    Abstract: Stacked devices and methods of fabrication are provided. Die-to-wafer (D2W) direct-bonding techniques join layers of dies of various physical sizes, form factors, and foundry nodes to a semiconductor wafer, to interposers, or to boards and panels, allowing mixing and matching of variegated dies in the fabrication of 3D stacked devices during wafer level packaging (WLP). Molding material fills in lateral spaces between dies to enable fan-out versions of 3D die stacks with fine pitch leads and capability of vertical through-vias throughout. Molding material is planarized to create direct-bonding surfaces between multiple layers of the variegated dies for high interconnect density and reduction of vertical height. Interposers with variegated dies on one or both sides can be created and bonded to wafers. Logic dies and image sensors from different fabrication nodes and different wafer sizes can be stacked during WLP, or logic dies and high bandwidth memory (HBM) of different geometries can be stacked during WLP.

    Abstract: Direct-bonded lamination for improved image clarity in optical devices is provided. An example process planarizes and plasma-activates optical surfaces to be laminated together, then forms direct bonds between the two surfaces without an adhesive or adhesive layer. This process provides improved optics with higher image brightness, less light scattering, better resolution, and higher image fidelity. The direct bonds also provide a refractory interface tolerant of much higher temperatures than conventional optical adhesives. The example process can be used to produce many types of improved optical components, such as improved laminated lenses, mirrors, beam splitters, collimators, prism systems, optical conduits, and mirrored waveguides for smartglasses and head-up displays (HUDs), which provide better image quality and elimination of the dark visual lines that are apparent to a human viewer when conventional adhesives are used in conventional lamination.

    Abstract: In one embodiment, an integrated device package is disclosed. The integrated device package can comprise a carrier an a molding compound over a portion of an upper surface of the carrier. The integrated device package can comprise an integrated device die mounted to the carrier and at least partially embedded in the molding compound, the integrated device die comprising active circuitry. The integrated device package can comprise a stress compensation element mounted to the carrier and at least partially embedded in the molding compound, the stress compensation element spaced apart from the integrated device die, the stress compensation element comprising a dummy stress compensation element devoid of active circuitry. At least one of the stress compensation element and the integrated device die can be directly bonded to the carrier without an adhesive.
