Method of making a device including a metallized magnetic substrate

A method for making a device including at least one magnetic component, the device comprising a metallized substrate of ceramic magnetic material, the method comprising:

• providing at least one layer of unfired magnetic ceramic material having a planar surface, said layer of unfired magnetic ceramic material to be referred to as the "unfired layer";
• creating at least one aperture through the unfired layer, the aperture having an inner side wall surface;
• coating said inner side wall surface with conductive material;
• forming a plurality of vias through the unfired layer such that the vias intersect at least one aperture edge removing the conductive material on portions of the aperture side wall defining at least one side wall conductive pathway;
• metallizing at least a portion of the planar surface of the unfired layer such that the metallized surface portion forms a continuous conductive region with the side wall conductive pathway to create a conductive winding about a portion of the unfired layer;
• and
• firing the unfired layer with the conductive winding formed thereon such that said metallized substrate of magnetic ceramic material results.
