  • Patent number: 7273812
    Abstract: Embodiments of the present invention are directed to the formation of microprobe tips elements having a variety of configurations. In some embodiments tips are formed from the same building material as the probes themselves, while in other embodiments the tips may be formed from a different material and/or may include a coating material. In some embodiments, the tips are formed before the main portions of the probes and the tips are formed in proximity to or in contact with a temporary substrate.

  • Publication number: 20070199822
    Abstract: Molded structures, methods of and apparatus for producing the molded structures are provided. At least a portion of the surface features for the molds are formed from multilayer electrochemically fabricated structures (e.g. fabricated by the EFAB™ formation process), and typically contain features having resolutions within the 1 to 100 ?m range. The layered structure is combined with other mold components, as necessary, and a molding material is injected into the mold and hardened. The layered structure is removed (e.g. by etching) along with any other mold components to yield the molded article. In some embodiments portions of the layered structure remain in the molded article and in other embodiments an additional molding material is added after a partial or complete removal of the layered structure.

  • Patent number: 7259640
    Abstract: RF and microwave radiation directing or controlling components are provided that may be monolithic, that may be formed from a plurality of electrodeposition operations and/or from a plurality of deposited layers of material, that may include switches, inductors, antennae, transmission lines, filters, and/or other active or passive components. Components may include non-radiation-entry and non-radiation-exit channels that are useful in separating sacrificial materials from structural materials. Preferred formation processes use electrochemical fabrication techniques (e.g. including selective depositions, bulk depositions, etching operations and planarization operations) and post-deposition processes (e.g. selective etching operations and/or back filling operations).

  • Publication number: 20070045121
    Abstract: In some embodiments, multilayer structures are electrochemically fabricated from at least one structural material (e.g. nickel), at least one sacrificial material (e.g. copper), and at least one sealing material (e.g. solder). In some embodiments, the layered structure is made to have a desired configuration which is at least partially and immediately surrounded by sacrificial material which is in turn surrounded almost entirely by structural material. The surrounding structural material includes openings in the surface through which etchant can attack and remove trapped sacrificial material found within. Sealing material is located near the openings. After removal of the sacrificial material, the box is evacuated or filled with a desired gas or liquid. Thereafter, the sealing material is made to flow, seal the openings, and resolidify. In other embodiments, a post-layer formation lid or other enclosure completing structure is added.

  • Publication number: 20060108678
    Abstract: Embodiments of invention are directed to the formation of microprobes (i.e. compliant electrical or electronic contact elements) on a temporary substrate, dicing individual probe arrays, and then transferring the arrays to space transformers or other permanent substrates. Some embodiments of the invention transfer probes to permanent substrates prior to separating the probes from a temporary substrate on which the probes were formed while other embodiments do the opposite. Some embodiments, remove sacrificial material prior to transfer while other embodiments remove sacrificial material after transfer. Some embodiments are directed to the bonding of first and second electric components together using one or more solder bumps with enhanced aspect ratios (i.e. height to width ratios) obtained as a result of surrounding the bumps at least in part with rings of a retention material. The retention material may act be a solder mask material.
