  • Integrated circuit inductor having a patterned ground shield
    Patent number: 8427266
    Abstract: An inductor structure can be implemented within a semiconductor integrated circuit (IC). The inductor structure can include a coil of conductive material having a first terminal and a second terminal each located at an opposing end of the coil. The inductor structure can include a patterned ground shield including a plurality of fingers implemented within an IC process layer located between the coil of conductive material and a substrate of the IC. The inductor structure also can include an isolation wall formed to encompass the coil and the patterned ground shield. The isolation wall can be coupled to one end of each finger.
    Type: Grant
