  • Patent number: 9678108
    Abstract: The method for forming a semiconductor probe tip comprises depositing a first copper layer onto exposed electrically conductive areas of a wafer. The first copper layer surrounds a non-conductive polymer structure on the wafer. The non-conductive polymer structure is removed to form a primary cavity in the first copper layer. The wafer and the primary cavity are coated with a polymer layer. Regions of the polymer layer are removed to form a secondary cavity within and alongside the primary cavity. A metal layer is deposited on exposed electrically conductive areas of the wafer and within bounds of the secondary cavity.

  • Patent number: 9250290
    Abstract: A method for testing a semiconductor device. The method comprises moving a probe in a vertical direction towards an electrical structure on a semiconductor device to position the probe alongside the electrical structure. A tip of the probe is positioned lower than an elevation of an outermost periphery of the electrical structure. The method also includes moving the probe in a lateral direction towards the electrical structure to contact the electrical structure. The probe tip mechanically and electrically engages the electrical structure.

  • Patent number: 8917106
    Abstract: Provided are microfabricated probe elements, including elastomer elements, and methods of making the same, that can be readily used with fine pitch microelectronic arrays, for instance by providing sufficient compliance in a small package, while minimizing deflection forces, and while precisely maintaining the planarity and positioning of the contact tips across vast grid arrays. Elastomer elements may be generated using photolithography, either directly or through a sacrificial lost-mold process. Elastomer probe elements are provided with rigid tip structures microfabricated thereon to improve contact pressure. A novel space transformation probe card assembly is also provided.
