NOVEL STACKED INDUCTOR AND ELECTRONIC COMPONENT MODULE HAVING THE NOVEL STACKED INDUCTOR

摘要

The present invention provides a novel stacked inductor and an electronic component module having the novel stacked inductor, wherein the multilayer stacked inductor is fabricated by stacking a top magnetic material layer, a plurality of first middle magnetic material layers, at least one second middle magnetic material layer, at least one non-magnetic material layer, and a bottom magnetic material layer. In the present invention, a second metal layer formed on the non-magnetic material layer and a first metal layer formed on the first middle magnetic material layer have a first line width ratio, and a third metal layer formed on the second middle magnetic material layer and the first metal layer have a second line width ratio. Therefore, the DC resistance and the quality factor of this novel multilayer stacked inductor can be optimized based on the first and second line width ratio.
