Patent ID: 7867787

Claim:
A method comprising: forming a first layer of magnetic material in an opening in a first dielectric layer; forming a barrier layer in a first via opening disposed in the first dielectric layer and then forming a conductive material on the barrier layer; forming a second dielectric layer on the first magnetic layer; forming at least one second via opening and at least one conductive structure opening in the second dielectric layer; forming a barrier layer in the at least one second via opening and in the at least one conductive structure opening, and then forming a conductive material in the at least one second via opening and in the at least one conductive structure opening; forming a third layer of dielectric material on the conductive material in the conductive structure opening; forming an opening in the third dielectric layer; and forming a second layer of magnetic material in the opening, wherein the first and second layers of the magnetic material are coupled to one another.
