Abstract
A 3D interconnect structure and method of manufacture are described in which metal redistribution layers (RDLs) are integrated with through-silicon vias (TSVs) and using a 'plate through resist' type process flow. A silicon nitride or silicon carbide passivation layer may be provided between the thinned device wafer back side and the RDLs to provide a hermetic barrier and polish stop layer during the process flow.
