Patents by Inventor Horng-Chieh Wang

Horng-Chieh Wang 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: 11300586
    Abstract: A probe head and a conductive probe thereof are provided. The conductive probe has a first long lateral edge and a second long lateral edge which define a central axis there-between. The conductive probe includes a middle segment, an upper connecting segment and a lower connecting segment respectively extending from the middle segment in two opposite directions, and an upper contacting segment and a lower contacting segment respectively extending from the upper and the lower connecting segments in two opposite directions. The lower contacting segment includes a testing tip having an offset with respect to the central axis and a curved surface connecting the testing tip and the second long lateral edge. A first distance between the testing tip and the first long lateral edge is less than a second distance between the testing tip and the second long lateral edge.

  • Patent number: 11125778
    Abstract: A probe head and a conductive probe thereof are provided. The conductive probe includes a first long lateral surface and an opposite second long lateral surface. The first long lateral surface and the second long lateral surface define a central axis there-between. The conductive probe includes a middle segment, an upper connecting segment and a lower connecting segment respectively extending from the middle segment in two opposite directions, and an upper contacting segment and a lower contacting segment respectively extending from the upper and the lower connecting segments in two opposite directions. The upper connecting segment includes an extension extending from the first long lateral surface in a direction away from the central axis. The upper contacting segment includes a protrusion extending from the first long lateral surface in a direction away from the central axis, and the extension and the protrusion are spaced apart from each other.

  • Patent number: 7012441
    Abstract: A conducting thin-film nanoprobe card fabrication method includes the steps of: (a) arranging nanotubes on a substrate in vertical; (b) covering the nanotubes with a liquid polymeric resin and then hardening the polymeric resin to form a conducting nanomembrane; (c) removing a part of the polymeric resin from the conducting nanomembrane to expose one end of each nanotube to outside; (d) removing the substrate and preparing a ceramic substrate having contacts at one side and metal bumps at the other side and plated through holes electrically respectively connected with the contacts and the metal bumps; (e) mounting the nanomembrane on the ceramic substrate to hold the nanotubes in contact with the contacts of the ceramic substrate, and (f) forming recessed holes in the nanomembrane by etching and inserting a metal rod in each recessed hole to form a respective probe.
