Abstract:
1. A bonded structure comprising: a first substrate having a first bonding-side surface and a first backside surface and a first sidewall surface; a second substrate having a second bonding-side surface and a second backside surface and a second sidewall surface, wherein said second substrate is bonded to said first substrate through a direct contact between said first bonding-side surface and said second bonding-side surface at an interface, wherein said interface does not extend to said first sidewall surface or said second sidewall surface; and a dielectric material layer laterally contacting said first sidewall surface at a periphery of said first substrate and said second sidewall surface at a periphery of said second substrate and contiguously extending from said first backside surface to said second backside surface, wherein said dielectric material layer contacts peripheral regions of said first bonding-side surface between said interface and said first sidewall surface and contacts peripheral regions of said second bonding-side surface between said interface and said second sidewall surface.
