Claim 0:
1. An integrated circuit (IC) structure, comprising:
a support structure, having a first side and a second side, opposite the first side;
a through-silicon via (TSV), extending between the first side and the second side;
a decoupling capacitor having a first capacitor electrode, a second capacitor electrode, and a capacitor insulator between the first capacitor electrode and the second capacitor electrode;
a liner of a dielectric material on sidewalls of the TSV; and
a liner of the dielectric material on sidewalls of the decoupling capacitor,
wherein:
the first capacitor electrode is a liner of a first electrically conductive material on sidewalls and a bottom of an opening in the support structure, the opening in the support structure extending from the second side towards, but not reaching, the first side,
the capacitor insulator is a liner of a capacitor insulator material on sidewalls and a bottom of the opening in the support structure lined with the first electrically conductive material,
the second capacitor electrode is a second electrically conductive material filling at least a portion of the opening in the support structure lined with the first electrically conductive material and with the capacitor insulator material, and
the liner of the dielectric material on sidewalls of the decoupling capacitor is between the first electrically conductive material and the sidewalls and the bottom of the opening in the support structure.
