At 412, the method 400 forms vias in a plurality of panel portions. The panel may include one or more sheets of insulator, for example, sheets of glass. The panel portions may be analogous to, for example, the top insulator 301, the middle insulator 302, and the bottom insulator 303 depicted in
It will be understood that the plurality of panel portions may include a first insulator and a second insulator, and that the forming at 412 may include forming respective vias through the first insulator and the second insulator.
At 414, the method 400 patterns and metallizes conductive layers on both sides of the plurality of panel portions.

The patterning and metallizing of the second conductor may further include electrically coupling the second top conductor to the second conductive sidewall and electrically coupling the second conductive sidewall to the second bottom conductor disposed on the second bottom surface of the second insulator.
It will be further understood that the patterning and metallizing at 414 may include forming horizontal coil portions and forming vertical coil portions of an inductor. For example, the forming of the horizontal coil portions may include patterning and metallizing a first plurality of parallel conductive portions on one or more of the first top surface and the first bottom surface of the first insulator and patterning and metallizing a second plurality of parallel conductive portions formed on one or more of the second top surface and the second bottom surface of the second insulator. The first plurality of parallel conductive portions may electrically couple two inductor vias in the first insulator and the second plurality of parallel conductive portions may electrically couple two second inductor vias in the second insulator. The forming of the vertical coil portions may include metallizing conductive sidewalls within the two first inductor vias in the first insulator and the two second inductor vias in the second insulator.
At 416, the method 400 metallizes the sidewalls of the vias formed at 414. The conductive sidewalls formed at 414 may be analogous to the top insulator sidewall conductive layer 313, the middle insulator sidewall conductive layer 323 and/or the bottom insulator sidewall conductive layer 333 depicted in

In some implementations, the insulative layer is applied at a same height as the inter-insulator conductive coupling provided at 422 and/or the inter-insulator dielectric coupling applied at 424. Moreover, the inter-insulator conductive coupling provided at 422 and/or the inter-insulator dielectric coupling applied at 424 are not embedded in the insulative layer applied at 426, but are instead exposed and configured for electrical coupling.
It will be understood that the applying at 426 may include applying an insulative layer to portions of the first insulator and the second insulator upon which the first conductor and second conductor are not disposed.
At 428, the method 400 stacks the plurality of panel portions. The stacking at 428 may be performed such that the vias formed at 412 in a particular panel portion of the plurality of panel portions is aligned with one or more vias formed at 412 in one or more adjacent panel portions of the plurality of panel portions. The stacking at 428 may be performed such that one or more of the conductive couplings provided to a particular panel portion at 422 and/or one or more of the dielectric couplings provided to the particular panel portion at 424 are coupled to one or more portions of the conductive layer patterned and metallized on an adjacent panel portion of the plurality of panel portions.

Additionally or alternatively, the stacking at 428 may include forming an inductor on and/or within the first insulator and the second insulator, for example, by providing a conductive coupling between the first insulator and the second insulator.
Moreover, the stacking at 428 may include vertically stacking the first insulator and the second insulator such that the respective vias, for example, the vias formed at 412, are vertically aligned. The stacking at 428 may further include electrically coupling the first bottom conductor to the dielectric layer and electrically coupling the dielectric layer to the second top conductor disposed on the second insulator.
As noted above, in some implementations, a single sheet of insulator may include each of the plurality of panel portions. Accordingly, the plurality of panel portions may optionally be singulated prior to the stacking at 428.
