Classification: CPC H | IPC H

Claim 0:
1. A method of forming a semiconductor device assembly, comprising:
forming at least one via in a core substrate, the at least one via extending from a first side of the core substrate to a second side of the core substrate, wherein the first side and the second side of the core substrate oppose each other;
forming an oxide layer over and in direct contact with the first side and the second side of the core substrate and a surface of the at least one via, wherein the surface of the at least one via is disposed between the first side and the second side of the core substrate;
disposing a dielectric material directly onto the oxide layer over the first side and the second side of the core substrate and the surface of the at least one via, wherein the dielectric material comprises an epoxy resin;
forming an opening through the dielectric material disposed over the surface of the at least one via, the opening defined by a surface extending between an exposed first surface of the dielectric material on the first side of the core substrate and an exposed second surface of the dielectric material on the second side of the core substrate, the dielectric material disposed between the surface of the formed opening and the surface of the at least one via; and
depositing a conductive layer over the surface of the formed opening.
