  • Publication number: 20180269380
    Abstract: An electrical contact structure and a method for forming the electrical contact structure are provided. The method includes forming a thin film material layer on a substrate, forming a first barrier layer on the thin film material layer and forming a metal layer on the first barrier layer. The method further includes patterning the metal layer to form a metal pattern, forming a spacer on a sidewall of the metal pattern and covering a portion of the first barrier layer. The method further includes etching the first barrier layer, wherein the portion of the first barrier layer located under the spacer is not completely etched. The method further includes removing the spacer and exposing the sidewall of the metal pattern to form an electrical contact structure on the thin film material layer, wherein the first barrier layer has a protrusion part exceeding the sidewall of the metal pattern.

  • Patent number: 9531218
    Abstract: A magnetic force generating device is provided for application to a first object that is movable relative to a second object providing a first magnetic force, and includes a coil disposed on the first object, a sensing module disposed on the first object adjacent to the coil for sensing a distance between the first and second objects, and a processor. When the sensed distance is shorter than a threshold value, the processor enables provision to the coil of a driving current having a magnitude negatively correlated to the sensed distance, so that the coil generates a second magnetic force, which is repulsive to the first magnetic force, in response to the driving current.
