Abstract:
A method of forming a capacitor, comprising:forming a first electrode layer overlying sidewalls of a via and at least a portion of a first surface of a substrate, wherein the sidewalls of the via are defined by a portion of the substrate extending from the first surface of the substrate to a second surface of the substrate, and wherein the first surface extends outwardly from the sidewalls; forming a dielectric layer overlying at least a first portion of the first electrode layer while leaving a portion of the via unfilled, wherein the first portion of the first electrode layer is within the sidewalls and at least a second portion of the first electrode overlying the first surface of the substrate remains uncovered by the dielectric layer; and forming a second electrode, wherein forming the second electrode comprises forming a conductive material completely filling the portion of the via left unfilled by the dielectric layer by electroless plating followed by electrolytic plating of a metal.
