Abstract
A method of fabricating an inductor includes (a) forming a ferromagnetic core on a semiconductor substrate, the ferromagnetic core lying in a core plane and (b) fabricating an inductor coil that winds around the ferromagnetic core, the inductor coil configured to generate an inductor magnetic field that passes through the ferromagnetic core in a first direction parallel to the core plane. While forming the ferromagnetic core, the method further includes (1) generating a bias magnetic field that passes through the ferromagnetic core in a second direction that is orthogonal to the first direction, and (2) inducing a magnetic anisotropy in the ferromagnetic core with the bias magnetic field.
