Claim 9:
10. The IC of claim 9, wherein:
the conductive structure comprises a first portion, a second portion, and a third portion;
the first portion is disposed laterally along the upper surface of the conductive feature of the interconnect structure;
the second portion overlies the first dielectric layer;
the third portion extends from the first portion to the second portion;
the third portion has a first sidewall;
the third portion has a second sidewall opposite the first sidewall of the third portion;
the first sidewall of the third portion and the second sidewall of the third portion are laterally spaced a first distance apart along a first plane;
the first sidewall of the third portion and the second sidewall of the third portion are laterally spaced a second distance apart along a second plane;
the first plane extends laterally in parallel with the second plane;
the first plane is disposed between the second plane and the semiconductor substrate; and
the second distance is greater than the first distance.
