Claim 11:
12. A method of forming a device, comprising:
providing a substrate;
arranging an interlevel dielectric over the substrate, wherein arranging the interlevel dielectric comprises:
forming a nitride block insulator over a first interlevel dielectric layer in an interconnect level i of the interlevel dielectric, wherein the first interlevel dielectric layer comprises a first interconnect and a second interconnect therein;
forming an opening in the nitride block insulator, the opening extending through the nitride block insulator to expose a surface of the first interconnect in the first interlevel dielectric layer;
forming a contact plug in the opening of the nitride block insulator, wherein the contact plug at least lines the opening and partially fills the opening, wherein the contact plug lines a bottom and sidewalls of the opening in the nitride block insulator without completely filling the opening, thereby preventing out-diffusion of conductive material from the first interconnect; and
forming a first film of a passive component over the nitride block insulator and over the contact plug, wherein the first film conforms to a topography of the nitride block insulator and the contact plug by directly lining a bottom and sidewalls of the contact plug in the opening and directly contacting the nitride block insulator beyond the opening.
