  • Patent number: 11983479
    Abstract: A method of fabricating an integrated circuit includes placing a first set of conductive feature patterns on a first level, placing a second set of conductive feature patterns on a second level, placing a first set of via patterns between the second set of conductive feature patterns and the first set of conductive feature patterns, placing a third set of conductive feature patterns on a third level different from the first level and the second level, placing a second set of via patterns between the third set of conductive feature patterns and the second set of conductive feature patterns, and manufacturing the integrated circuit based on at least one of the above patterns of the integrated circuit.

  • Patent number: 6594450
    Abstract: A camera auto-focus mechanism includes a frame having a first hollow cylinder. A second hollow cylinder including metal material is fit over the first cylinder and capable of moving relative to the first cylinder. A first lens is fixed to the frame, and a second lens is fixed inside the second cylinder, both lenses being axially aligned with the cylinders. An insulated conductive metal coil is wound around the first cylinder, and a spring joins the second cylinder and the first cylinder. When current is not applied to the coil, the second cylinder is held in a first position by the spring such that the first and second lenses form a first focal length. And, when current is applied to the coil, the second cylinder is held in a second position against a force of the spring such that the first and second lenses form a second focal length.
