    Abstract: An opening is formed within a dielectric material overlying a semiconductor substrate. The opening may comprise a via portion and a trench portion. During the manufacturing process a treatment chemical is placed into contact with the exposed surfaces in order to release charges that have built up on the surfaces. By releasing the charges, a surface change potential difference is reduced, helping to prevent galvanic corrosion from occurring during further manufacturing.

  • Patent number: 10207138
    Abstract: A resistance device applied to relative rotations between a flywheel and an axis includes an inner stator, an outer rotor, a conductive wire and a magneto-rheological fluid. The inner stator is fixedly joined with the axis and includes an accommodating space surrounding the axis at a position away from the axis. The outer rotor, fixedly joined with the flywheel, encloses and rotates relative to the inner stator. An accommodating gap is formed between the outer rotor and the inner stator at a position away from the axis. The conductive wire is wound in the accommodating space, and generates a magnetic line passing the accommodating gap when applied by an electric current. The magneto-rheological fluid is filled in the accommodating gap. Thus, the outer rotor is disposed at the outer most region of the resistance device to increase the braking torque, and the magneto-rheological fluid is away from the axis to increase the braking moment.
