Abstract:
1. A method, comprising: forming a first inductor in a first dielectric layer over a substrate, the first inductor having an at least one trench, the at least one trench having a pair of walls and a bottom; forming a first conductor over the first inductor, the first conductor defining a first signal path along the pair of walls and the bottom of the dielectric layer; forming a first magnetic layer over the dielectric layer, the first magnetic layer defining a second signal path parallel to the first signal path; forming a second inductor in the dielectric layer over the substrate, the second inductor having an at least one trench, the at least one trench having a pair of walls and a bottom; forming a second conductor over the second inductor, the second conductor defining a third signal path along the pair of walls and the bottom of the dielectric layer; forming a second magnetic layer over the dielectric layer, the second magnetic layer defining a fourth signal path parallel to the third signal path.
