Assignee: INTEL CORPORATION
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. An integrated circuit (IC) package, comprising:
an IC die having a first side and a second side, opposite the first side; and
a further IC component, coupled to the IC die,
wherein:
a through-silicon via (TSV) extends between the first side and the second side,
the IC die includes 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,
the first capacitor electrode is a liner of a first electrically conductive material on sidewalls and a bottom of an opening in the IC die, the opening in the IC die extending from the second side towards, but not reaching, the first side of the IC die,
the capacitor insulator is a liner of a capacitor insulator material on sidewalls and a bottom of the opening in the IC die 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 IC die lined with the first electrically conductive material and with the capacitor insulator material,
the TSV is at least partially filled with a third electrically conductive material, and
the IC die further includes a liner of a dielectric material on sidewalls of the TSV and a liner of the dielectric material on the sidewalls of the opening in the IC die, wherein the liner of the dielectric material on the sidewalls of the opening in the IC die is between the sidewalls of the opening in the IC die and the liner of the first electrically conductive material.
