Abstract
Provided is a monolithic stacked integrated circuit (IC). The IC includes a first layer over a substrate and a second layer over the first layer. The first layer includes a first plurality of circuit elements where a first portion of the first plurality of circuit elements has defects. The second layer includes a second plurality of circuit elements. The IC further includes interconnect elements coupling the first portion to a second portion of the second plurality of circuit elements for mitigating the defects.
