| Zusammenfassung: | A coil with a plurality of conductors has a width much bigger than a thickness in a 3D structure. The plurality of conductors forms a conductive structure having a top conductive portion formed on a first planar surface, a first edge conductive portion formed along a first sidewall, a bottom conductive portion formed on a second planar surface and a second edge conductive portion formed on a second sidewall. The top conductive portion and the first edge conductive portion form a first L-shaped structure, the bottom conductive portion and the second edge conductive portion form a second L-shaped structure, and the first L-shaped structure and the second L-shaped structure are configured to form a low ac resistance structure. The coil also has an insulation material inside the conductive structure and a plurality of terminals formed with the plurality of conductors for connecting the coil. |
