Patent attributes
Methods of directly bonding a first semiconductor structure to a second semiconductor structure include directly bonding at least one device structure of a first semiconductor structure to at least one device structure of a second semiconductor structure in a conductive material-to-conductive material direct bonding process. In some embodiments, at least one device structure of the first semiconductor structure may be caused to project a distance beyond an adjacent dielectric material on the first semiconductor structure prior to the bonding process. In some embodiments, one or more of the device structures may include a plurality of integral protrusions that extend from a base structure. Bonded semiconductor structures are fabricated using such methods.
