    Abstract: A semiconductor package applicable to integrated circuits and other semiconductor devices of the kind needing high integration and high speed operation. The package has a printed circuit board implemented by a glass cloth impregnated with epoxy, bismaleimide-triazine (BT) or similar resin, a power source layer provided in the circuit board in a plate structure, a ground layer formed on the surface of the circuit board in a plate structure, and a thin film laminate wiring formed on the ground layer in a plate structure and consisting of copper and benzocyclobutene. The package desirably shields leakage currents and matches a characteristic impedance with accuracy, thereby noticeably reducing noise and enhancing high speed signal transmission.

    Abstract: A process for manufacturing a thin film circuit board includes forming an insulator layer having a relatively high etching rate in a desired thickness on an insulator layer having a relatively low etching rate and a relatively high dielectric constant, arranging a conductor layer on the insulator layer having a relatively high etching rate, selectively removing the insulator having a relatively high etching rate by etching but excluding a portion located beneath the conductor layer, forming an insulator portion that contains the insulator layer having a relatively high etching rate and supports the conductor layer in the undercut state, forming an insulator layer having a relatively low dielectric constant so as to surround the entire conductor layer, and forming an insulator layer having a relatively high dielectric constant on top of the insulator layer having a relatively low dielectric constant so as to surround the entire insulator layer having a relatively low dielectric constant.

    Abstract: 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.

    Abstract: The present invention is an integrated heat sink module and a method of fabricating conductive structures on a substrate. The method of the present invention includes cleaning a substrate material to remove any impurities present on the substrate surface. The method further includes placing a protective layer resilient to chemicals used in conductive structure formation, on a first surface. The first surface is opposite a second surface on which conductive structures are formed. The method includes forming conductive structures on the second surface of the substrate. The protective layer is then removed from the first surface of the substrate.
