  • Patent number: 8717054
    Abstract: Embodiments disclosed herein are directed to compliant probe structures for making temporary or permanent contact with electronic circuits and the like. Some embodiments are directed to various designs of cantilever-like probe structures while other embodiments are directed to methods for fabricating probe structures. In some embodiments, methods of forming probe structures include formation of a plurality of planar multi-material electrodeposited layers wherein each probe structure includes a contact tip and a compliant body, wherein the compliant body is formed from at least one material that is different from the contact tip material and wherein the compliant body provides for elastic compression of the probe in a plane of primary motion during use and wherein during formation of the layers a stacking direction of the plurality of layers is perpendicular to the plane of primary motion.

  • Patent number: 8713788
    Abstract: Multi-layer, multi-material fabrication methods include depositing at least one structural material and at least one sacrificial material during the formation of each of a plurality of layers wherein deposited materials for each layer are planarized to set a boundary level for the respective layer and wherein during formation of at least one layer at least three materials are deposited with a planarization operation occurring before deposition of the last material to set a planarization level above the layer boundary level and wherein a planarization occurs after deposition of the last material whereby the boundary level for the layer is set. Some 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).

  • Patent number: 7878385
    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.

  • Publication number: 20100288186
    Abstract: Techniques are generally disclosed for forming crystalline bodies. An example system, device or method for forming crystalline bodies may include a crucible for containing molten crystalline material and a support for accommodating a seed on an end thereof, the support being movable along a translation axis in a pull direction to draw the seed crystal from the molten crystalline, thereby initiating growth of a crystalline body along a growth path. Further examples may include one or more nozzles configured to be coupled to a fluid source, the nozzles being positioned relative to the growth path for shaping the crystal body as the molten crystalline is pulled in the pull direction along the growth path.

  • Publication number: 20100213068
    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 EFABâ„¢ 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.

  • Publication number: 20100133109
    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.
