    摘要: A three dimensional thin-film interconnector is fabricated by depositing a dielectric layer onto the surface of a substrate, depositing a layer of conductive material onto the dielectric layer to form a signal plane, depositing a dielectric layer onto the surface of the signal plane, forming a plurality of through holes in the dielectric layer that extend to the signal plane, and filling the through holes with an electrically conductive material to form vias. The sequence of forming a signal plane, depositing a dielectric layer, forming a plurality of through holes, and filling the through holes is repeated until a predetermined number of signal planes and a predetermined arrangement of vias are obtained. The through holes are formed at locations in the dielectric layers corresponding to both predetermined electrical connections and the vias in a preceding dielectric layer. The signal planes are formed at different locations on the substrate. The sequence of signal planes and dielectric layers at the same location on the substrate form a signal plane set which defines a connector. Contact pads are deposited onto the surface of a final dielectric layer and electrically connect with each via. Wires are used to electrically connect the contact pads of one connector to corresponding contact pads of another connector. A portion of the substrate and dielectric layers not comprising a signal plane set is removed, forming electrical connectors flexibly attached by the plurality of wires.

    摘要: A thin-film bypass capacitor is fabricated by forming a plurality of through holes through the thickness of a nonconductive base substrate and filling the through holes with a conductive material to form ground vias and power vias. A sequence of back side metalization layers are applied to the back side surface of the base substrate. A sequence of bottom contact layers are applied to the front side surface of the base substrate. A bottom contact power terminal is formed and a bottom contact metalization layer is applied to the surface of the bottom contact layers. A portion of the metalization layer is removed and an insulating layer is formed on the surface of the bottom contact metalization layer. A ground metalization feedthrough and a power metalization feedthrough are formed at the surface of the insulating layer. A sequence of top contact layers are applied to the surface of the insulating layer and a front side ground terminal and front side power terminal are formed. A back side ground terminal and a back side power terminal are formed at the back side of the base substrate.

    摘要: Methods of etching polyamic acid layers and the like are disclosed. In exemplary embodiments of the present invention, the polymeric acid layer to be etched is alternatively exposed to etchant solutions (etchants) and rinse solutions, where the etchant solutions are of relatively moderate alkalinity and the rinse solutions have a lower pH than the etchant solutions. The present invention enables polymeric acid layers to be developed with standard basic etchants at relatively moderate concentrations and at room temperature with little, if any, corrosion to any underlying metal layers. The present invention enables the more reliable and cleaner spin-spray processing method to be employed, thereby significantly increasing yields and reducing overall processing costs. The present invention also enables the etching of thick layers of polymeric acid without the need for special treatments, such as exposure to highly concentrated etchant solutions or high temperature processing conditions.
