Abstract: An electromagnetic component including a multi-layer, spiral coil structure embedded in a molded body is disclosed. Each layer of the coil structure makes approximately one and a quarter turns of a winding. Each layer of the coil structure has a loose middle segment, two slim end segments overlapping each other with a spacing therebetween, and tapered neck segments respectively connecting the loose middle segment with the two slim end segments.

Abstract: A method of manufacturing a multi-layer coil includes steps of providing a substrate; forming a seed layer on the substrate; and plating the seed layer with N coil layers by N current densities according to N threshold ranges, so as to form the multi-layer coil on the substrate, wherein an i-th current density of the N current densities is lower than an (i+1)-th current density of the N current densities. A first coil layer of the N coil layers is plated on the seed layer by a first current density of the N current densities. When an aspect ratio of an i-th coil layer of the N coil layers is within an i-th threshold range of the N threshold ranges, an (i+1)-th coil layer of the N coil layers is plated on the i-th coil layer by the (i+1)-th current density.
