  • Publication number: 20090261937
    Abstract: An integrated inductor includes a winding consisting of an aluminum layer atop a passivation layer, wherein the aluminum layer does not extend into the passivation layer and has a thickness that is not less than about 2.0 micrometers. The passivation layer has a thickness not less than about 0.8 micrometers. By eliminating copper from the integrated inductor and increasing the thickness of the passivation layer, the distance between the bottom surface of the inductor structure and the main surface of the semiconductor substrate is increased, thus the parasitic substrate coupling may be reduced and the Q-factor may be improved. Besides, the increased thickness of the aluminum layer may help improve the Q-factor as well.
