| 摘要 |
A semiconductor device (118) and method of fabrication thereof, wherein a plurality of conductive lines (124) are formed over a workpiece, a surface-smoothing conductive material (140) is disposed over the conductive lines (124), and a magnetic material (132) disposed is over the surface-smoothing conductive material (140). The surface-smoothing conductive material (140) has a smaller grain structure than the underlying conductive lines (124). The surface-smoothing conductive material (140) is polished so that the surface-smoothing conductive material (140) has a texturally smoother surface than the surface of the conductive lines (124).
