Cheng-San WU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11415457
    Abstract: The present invention provides a vibration sensor, which comprises a circuit board having an accommodating space. A sensing assembly is disposed in the accommodating space. A recess for magnet sliding is disposed in the sensing assembly. Dispose a magnet in the recess and then dispose a coil layer on an arbitrary side or both sides of the sensing assembly. Furthermore, a lubricating layer is coated on the recess. Alternatively, the recess can be a vacuum structure or a hollow cross-sectional structure for reducing the friction between the recess and the magnet. Alternatively, the coil layer can be coated with a protective layer or multiple layers can be stacked. Without increasing the area of the sensor, the sensing on the variation of magnetic flux can be improved. Accordingly, the vibration sensor according to the present invention can achieve wideband detection of vibrations.

  • Patent number: 8679728
    Abstract: A method for fabricating a patterned layer is disclosed. Firstly, a semiconductor substrate is provided. Then, a precursory gas on the semiconductor substrate is formed. Finally, a patterned layer on the semiconductor substrate is deposited by reacting the precursory gas with at least one electron beam or at least one ion beam. The present invention not only fabricates a patterned layer on the substrate in a single step but also achieves a high lithographic resolution and avoids remains of contaminations by using the properties of the electron beam or the ion beam and the precursory gas.

  • Publication number: 20100233437
    Abstract: A lithographic machine platform and applications thereof is disclosed. The lithographic machine platform comprises: an electron beam or an ion beam generator generating an electron beam or an ion beam; a substrate supporting platform supporting a substrate; and a precursory gas injector injecting a precursory gas above the substrate. The present invention uses the electron beam or the ion beam to induce the precursory gas to react with the electron beam or the ion beam, and then the precursory gas is deposited on the substrate. The present invention not only fabricates a patterned layer on the substrate in a single step but also achieves a high lithographic resolution and avoids remains of contaminations by using the properties of the electron beam or the ion beam and the precursory gas.
