Abstract
Vertical type structures for integrated circuit inductors are disclosed. These vertical type inductors include the single-loop type, the parallel-loop type and the screw type, which form three different embodiments in the present invention. In the first embodiment, three-dimensional type structures, a single-loop type is utilized as an integrated circuit inductor. This inductor structure is formed on a substrate and the axis of the structure is upright to the substrate. In another embodiment according to the present invention, a parallel-loop type structure for radio frequency (RF) integrated circuit inductor is provided. A screw type structure according to this invention is the third embodiment. It features an axis that is parallel to the surface of the substrate and threads into the semiconductor device.
