Patent ID: 7584533

Claim:
A method of fabricating an inductor structure on an integrated circuit structure, the method comprising: forming a passivation layer over the integrated circuit structure; forming a segmented, bottom magnetic core element over the passivation layer, the bottom magnetic core element having a longitudinal axis; forming a conductive inductor coil element over the bottom magnetic core element and separated therefrom by intervening dielectric material; forming a segmented, top magnetic core element over the inductor coil element and separated therefrom by intervening dielectric material, the top magnetic core element having a longitudinal axis that is parallel to the longitudinal axis of the bottom magnetic core element; and wherein the inductor coil element is formed to be orthogonal to the longitudinal axis of the bottom and top magnetic core elements, an easy axis of the bottom and top magnetic core elements is parallel to the inductor coil element, and a hard axis of the bottom and top magnetic core elements is parallel to the longitudinal axis of the bottom and top magnetic core elements.
