    摘要: A contact structure and assembly for a microelectronics device includes first and second electrically conductive contacts being helically shaped. A carrier element is attached to and positioned between the first and second contacts. The first and second contacts are in electrical communication with each other, and the first and second contacts are in a mirror image relationship with each other. A pair of insulating substrates each include electrically conductive members. A contact point on each of the first and second contacts is attached and electrically communicating to respective electrically conductive members such that the first and second electrically conductive contacts between the pair of insulating substrates form an electrically conductive package. A metal layer on the carrier element provides electrical conductivity through a first opening defined by the carrier element between the first and second portions of the helix shaped contact.

    摘要: A negative electrophoretic photoresist is applied over a plurality of protruding disposable template portions on a substrate. A silo structure is placed on planar portions of the negative electrophoretic photoresist that laterally surround the plurality of protruding disposable template portions. The negative electrophoretic photoresist is lithographically exposed employing the silo structure and a first lithographic mask, which includes a transparent substrate with isolated opaque patterns thereupon. After removal of the silo structure, the negative electrophoretic photoresist is lithographically exposed employing a second lithographic mask, which includes a pattern of transparent areas overlying the planar portions of the negative electrophoretic photoresist less the areas for bases of metal structure to be subsequently formed by electroplating. The negative electrophoretic photoresist is developed to form cavities therein, and metal structures are formed by electroplating within the cavities. The negative electrophoretic photoresist and the plurality of protruding disposable template portions can be subsequently removed.
