Abstract
A reconfigurable multi-stack inductor formed within a semiconductor structure may include a first inductor structure located within a first metal layer of the semiconductor structure, a first ground shielding structure located within the first metal layer that is electrically isolated from and circumferentially bounds the first inductor structure, and a second inductor structure located within a second metal layer of the semiconductor structure, whereby the second inductor structure is electrically coupled to the first inductor structure. A second ground shielding structure located within the second metal layer is electrically isolated from and circumferentially bounds the second inductor structure, whereby the first and second inductor generate a first inductance value based on the first ground shielding structure and second ground shielding structure being coupled to ground, and the first and second inductor generate a second inductance value based on the first ground shielding structure and second ground shielding structure electrically floating.

11. A method of forming a reconfigurable multi-stack inductor structure within a semiconductor structure having a first and a second metal layer, the method comprising:
-
forming, within the first metal layer, a first inductor structure; forming, within the first metal layer, a first ground shielding structure that is electrically isolated from and circumferentially bounds the first inductor structure; forming, within the second metal layer, a second inductor structure; electrically coupling the first inductor structure and second inductor structure; forming, within the second metal layer, a second ground shielding structure that is electrically isolated from and circumferentially bounds the second inductor structure; electrically grounding the first and the second ground shielding structure to generate a first inductance value; and electrically floating the first and the second ground shielding structure to generate a second inductance value. - View Dependent Claims (12, 13, 14, 15, 16, 17)
