Abstract:
A semiconductor device having a semiconductor substrate and a first insulator overlying the semiconductor substrate. A spiral coil inductor overlies the first insulator and a second insulator overlies the spiral coil inductor. A patterned ferromagnetic film overlies the second insulator and a patterned magnetic-bias film overlies the patterned ferromagnetic film.
