Abstract
A method for producing an integrated circuit wherein a substrate is provided that includes a circuit structure and a first metalization structure disposed thereover comprising at least one layer with plated holes extending therethrough and into the circuit structure. The plated holes are insulated and a planarizing layer is disposed over the metalization structure. A handling wafer is applied over the substrate permitting the substrate to be thinned such that metalized connections disposed in the plated holes are exposed. A second metalization structure is provided and connected to the circuit structure and/or the first metalization structure by the metalized connections.
