Abstract:
A method comprising:forming a first via hole in a first substrate; introducing metal on a first surface and a second surface of the first substrate, the metal introduced on the first surface of the first substrate is layered over the first via hole and comes in contact with the metal introduced on the second surface of the first substrate; patterning signal lines in the introduced metal on the first surface and the second surface of the first substrate, wherein the patterned signal lines in the introduced metal on the first surface and the second surface of the first substrate forms a first metal pattern; attaching a first dielectric to the first surface of the first substrate, wherein the dielectric is in contact with the first metal pattern and the first surface of the first substrate; electronically connecting a portion of the signal lines of the first substrate and the dielectric; attaching an electrical element to the second surface of the first substrate, wherein the electrical element is one of a passive and an active electrical element; removing a portion of the electrical element to reduce the thickness of the electrical element; attaching a second dielectric to the second surface of the first substrate, wherein the second dielectric is in contact with the active electrical element and the second surface of the first substrate and the second dielectric surrounds the electrical element and has a thickness equivalent to the remaining portion of the electrical element.
