Claim Text:
1. A method for forming a multilayer device, the method comprising: providing a core substrate having opposing first and second core surfaces; forming a top and a bottom inner conductive pattern on each of the first and second core surfaces, respectively; forming a first dielectric layer on at least a portion of the first core surface, and the top inner conductive pattern; forming a second dielectric layer on at least a portion of the second core surface, and the bottom inner conductive pattern; laminating the first and second dielectric layers with top and bottom outer conductive layers, respectively; providing a first via through the core substrate, wherein the first via extending from the top outer conductive layer to the bottom outer conductive layer; and attracting, by a magnetic force, at least one solder coated magnetic particle into the first via.
