Abstract:
1. An apparatus, comprising: a first substrate; first conductors disposed over the first substrate and each having a first contact and a second contact, the first contacts approximately aligned with each other and the second contacts approximately aligned with each other; a first insulating layer covering the first conductors and having a first top surface with a plurality of first openings in the first top surface exposing the first and second contacts of the first conductors; a second substrate; second conductors disposed over the second substrate and each having a first contact and second contact, the first contacts approximately aligned with each other and the second contacts approximately aligned with each other; a second insulating layer covering the second conductors and having a second top surface with a plurality of second openings in the second top surface exposing the first and second contacts of the second conductors; wherein the first and second top surfaces face each other with the first openings aligned with each other and the second openings aligned with each other; and a plurality of solder bumps within the aligned first and second openings to electrically connect the first and second conductors to form an inductor.
