    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: A high density through-hole interconnect with high aspect ratio vias is formed by sequentially forming layers of dielectric material on a previous dielectric layer. After each layer is formed, a plurality of through holes are etched through each layer and filled or metalized with an electrically conductive material having a coefficient of thermal expansion matching that of the dielectric layers and the integrated circuit that it will connect with. Preferably, the process of forming dielectric layers, forming through holes, and metalizing the through holes is repeated until the metalized through holes have an aspect ratio in the range of from 6 to 10. A support structure is constructed to interconnect with and support the metalized vias while the dielectric material is removed. A second dielectric material having the desired mechanical and electrical properties is poured into the support structure to fill the space between the metalized vias and allowed to solidify. The support structure is removed and the through-hole interconnector, comprising the metalized vias and the second dielectric material, is lapped and polished to predetermined manufacturing dimensions and tolerances.

    摘要: An interconnecting post for mounting a microelectronic device such as an integral circuit chip is fabricated with generally uniform cross-section, by forming a first layer of positive photoresist on a substrate, soft-baking that first layer and exposing it for a short time with a wide-apertured mask or simply a UV blank flood exposure. Without developing the first layer, a second layer of positive resist is then applied over the first layer, soft-baked, and then exposed with a narrow-apertured mask. During the soft-baking of the second layer, some of its activator in the photoresist compound diffuses into the exposed portion of the first layer and modifies its solubility in such a way that, when the layers are subsequently developed, the developer partially undercuts the unexposed portion of the first layer to form in the photoresist an opening of generally uniform cross-section. This opening can then be filled by plating to produce a strong, integral interconnect post.
