Abstract:
1. A method of manufacturing a multilayer inductor comprising the steps of: forming external and internal vias in a plurality of magnetic green sheets; printing and curing conductive patterns on the plurality of magnetic green sheets; stacking and pressing the plurality of magnetic green sheets together to form an internal inductor element and external signal/power routes; firing and baking the plurality of stacked and pressed plurality of magnetic green sheets; singulating the plurality of magnetic green sheets; and plating external conductive patterns on the plurality of multilayer inductors, and further comprising the multi-layer inductor accommodating a semiconductor chip in a flip chip configuration, and wherein each layer of the at least one multi-layer inductor contains ⅞ turns of conductive trace on one surface except for the top layer.
