Abstract:
1. A method comprising: forming a first passivation layer over a first conductive feature and a second conductive feature; etching the first passivation layer to expose the first conductive feature, wherein the second conductive feature remains to be covered by the first passivation layer; forming a first polymer layer over the first passivation layer; patterning the first polymer layer to form a first opening and a second opening, wherein the first conductive feature is exposed through the first opening, and a top surface of a portion of the first passivation layer overlapping the second conductive feature is exposed to the second opening; and forming a conductive material to simultaneously fill the first opening and the second opening with a first portion and a second portion of the conductive material, respectively, wherein the first portion of the conductive material is electrically coupled to the first conductive feature, and the second portion of the conductive material forms a capacitor with the second conductive feature.
