Abstract:
1. A method comprising bonding a pair of substrates together with a plurality of bonding structures on each said substrate, wherein: the plurality of bonding structures on each said substrate is respectively interlocked one to the other in a mating position; each said bonding structure is selected from the group consisting of a dove tail bonding structure and a T-shaped bonding structure; and at least one of the substrates includes an integrated circuit, wherein the bonding a pair of substrates together further comprises: forming a layer of a material upon a stack of films over one of the substrates; and forming the plurality of bonding structures from the layer of the material, wherein forming the plurality of bonding structures from the layer of the material comprises: masking the layer of the material; forming both implanted and unimplanted regions in the layer of the material; and patterning the layer of the material with a process that is selective to either the implanted material or the unimplanted material, whereby there is removed one of the implanted and unimplanted regions in the layer of the material at a higher material removal rate than the other, whereby there are formed a plurality of dove tail bonding structures.
