Claim 9:
10. An apparatus comprising:
a laminate including:
a dielectric layer having a first surface and a second surface opposed to the first surface;
a first conductive layer forming a first transformer coil overlying the first surface of the dielectric layer; and
a second conductive layer forming a second transformer coil overlying the second surface of the dielectric layer;

a patterned magnetic layer over the first conductive layer,
wherein a first edge surface of the patterned magnetic layer is coplanar with a first edge surface of the laminate, and
wherein a second edge surface of the first magnetic layer is coplanar with a second edge surface of the laminate; and
a non-patterned magnetic layer over the second conductive layer,
wherein a first edge surface of the non-patterned magnetic layer is coplanar with the first edge surface of the laminate, and
wherein a second edge surface of the second magnetic layer is coplanar with the second edge surface of the laminate.
