  • Patent number: 5370766
    Abstract: The fabrication of thin film inductors on a substrate, which may include thin film resistors, thin film capacitors, and semiconductor devices. In one embodiment an inductor is fabricated initially on a substrate and then integrated with other devices subsequently formed on the substrate. In this embodiment, process steps used to fabricate such other devices utilize temperatures sufficiently low to prevent damaging or destroying the characteristics of the inductor. In another embodiment the fabrication of an inductor is achieved through photoresist masking and plating techniques. In alternative embodiments, fabrication of an inductor is achieved by sputtering, photoresist processes and etching/ion-milling techniques. A combination of various individual process steps from various embodiments are suitable for use to fabricate the individual layers to achieve a structure of this invention.
