Abstract:
A high capacitance embedded metal interconnect capacitor and associated fabrication processes are disclosed for using a directional barrier metal formation sequence in a dual damascene copper process to form multi-layer stacked copper interconnect structure having reduced barrier metal layer formation at the bottom of each via hole so that the multi-layer stacked copper interconnect structure may be readily removed and replaced with high capacitance MIM capacitor layers.

Abstract:
An integrated circuit device and associated fabrication process are disclosed for forming a through semiconductor via (TSV) conductor structure in a semiconductor substrate with active circuitry formed on a first substrate surface where the TSV conductor structure includes multiple small diameter conductive vias extending through the first substrate surface and into the semiconductor substrate by a predetermined depth and a large diameter conductive via formed to extend from the multiple small diameter conductive vias and through a second substrate surface opposite to the first substrate surface.
