Claim 9:
10. An integrated circuit chip of claim 1, further comprising:
a front end of line (FEOL) structure;
a back end of line (BEOL) structure over the FEOL structure;
wherein the BEOL structure includes:
a last metal structure providing a bonding pad;
a passivation structure covering a peripheral region of the last metal structure and including a first opening extending through the passivation structure and exposing an upper surface of the last metal structure;
a conformal nitride layer extending over the passivation structure and in contact with the upper surface of the last metal structure;

an insulator material layer covering the conformal nitride layer and including a second opening extending through both the insulator material layer and the conformal nitride layer, where a foot portion of the conformal nitride layer on the upper surface of the last metal structure is self-aligned with the second opening; and
a passive circuit component having a terminal electrically connected to the last metal structure.
