Patent ID: 8826514

Claim:
A method for producing an inductor comprising the steps of: providing a first substrate having a first side and a second side opposing the first side of the first substrate; forming a first plurality of vias in the first substrate; filling the first plurality of vias in the first substrate with a first plurality of metal fillings; forming a first plurality of metal conductors on the first side of the first substrate; connecting pairs of the first plurality of metal fillings together using the first plurality of metal conductors; providing a second substrate having a first side and a second side opposing the first side of the second substrate; forming a second plurality of vias in the second substrate; filling the second plurality of vias in the second substrate with a second plurality of metal fillings; forming a second plurality of metal conductors on the first side of the second substrate; connecting pairs of the second plurality of metal fillings together using the second plurality of metal conductors; bonding the second side of the first substrate with the second side of the second substrate after performing the step of filling the second plurality of vias in the second substrate with the second plurality of metal fillings; and connecting the first plurality of metal fillings to the second plurality of metal fillings to form a spiral.
