  • Patent number: 5491304
    Abstract: A connector is disclosed for electrically coupling groups of contact points formed on a first and second electronic circuit chip. The connector is constructed by applying a layer of dielectric material to a planar electrically conductive base, lithographically printing a pattern onto the dielectric material, etching the pattern and creating a plurality of wells extending through the dielectric material and a matching plurality of cavities in the surface of the base, and electroplating the pattern and filling the wells with an electrically conductive electroplate material. The electroplate thereby forms a plurality of conductive members, each extending through the dielectric material. The base is then removed from the dielectric material, thereby forming a connector board having the conductive members extending therethrough for electrically coupling the first and second groups of contact points on the circuit chips.

  • Patent number: 5382759
    Abstract: An electrical interconnect and a method of fabricating an electrical interconnect are provided. A first transparent dielectric layer is disposed on top of a support structure. A conductive circuit layer is plated above the first dielectric layer. Separate conductive layers are plated on top of the conductive circuit layer to produce conductive vias. A second transparent dielectric layer is disposed around the conductive layers. Contact tips are electrically connected to the top surface of the separate conductive layers. The interconnect may be visually aligned so that the contact tips brought into contact with target connections. In addition, the support structure may be partially removed to allow a flexible interconnect.
