Claim Text:
1. A method of forming a device comprising: providing a substrate defined with at least first and second regions; providing a first upper dielectric layer over the substrate, wherein the first upper dielectric layer comprises a first upper interconnect level with a plurality of metal lines in the first and second regions; providing a dielectric layer over the first upper dielectric layer, wherein the dielectric layer comprises a second upper interconnect level with a plurality of metal lines in the first and second regions; forming a magnetic random access memory (MRAM) cell, wherein the MRAM cell is disposed between the first and second upper interconnect levels in the first region; and forming an inductor in the second region, wherein the inductor comprises a lower inductor level formed from the metal lines in the first upper interconnect level and an upper inductor level formed from the metal lines in the second upper interconnect level, wherein the metal lines in the lower inductor level and upper inductor level are coupled by via contacts to form loops of the inductor.
