    摘要： A technique for forming an organic chip carrier or circuit board, having two voltage planes and at least two signal planes is provided which includes bonding a first layer of photolithographic dielectric material to a first metal layer and exposing the first layer of dielectric material to a pattern of radiation to provide at least one opening through the first layer of the dielectric material. A second metal layer is bonded to the first layer of photoimageable material on the opposite side from the first metal layer. Holes are etched in the first and second metal layers which correspond to and are larger than each of the patterns on said openings in the first layer of dielectric material. The exposed pattern on the first layer of dielectric material is then developed, with the openings in the first and second metal layers being larger than the corresponding developed opening in the first dielectric material. Second and third layers of photoimageable dielectric material are applied on the first and second metal layers, respectively and are photopatterned and developed to provide openings in each of the second and third layers of dielectric material some of which correspond to each of the holes in the first layer of dielectric material and the holes in the first and second metal layers, some of which terminate at the underlying metal layer. The exposed surfaces of both the second and third dielectric material, are circuitized and the holes plated or filled with metal.

    摘要： A cavity-type chip module. The module is formed with an adhesive joining layer of photoimageable material interposed between a metal stiffener and a laminate top layer with a central aperture defined in the top layer. The photoimageable material is exposed to actinic radiation, except for an area corresponding to the aperture in the top layer. The unexposed area of photoimageable material is developed away to form a window in the joining layer. The top layer, joining layer, and stiffener are laminated together with the window and aperture aligned, and with a portion of the stiffener spanning the aperture to define a cavity in the resulting substrate. The removal of the unexposed photoimageable material, and the selective exposure of the joining layer to actinic radiation, keep the cavity free of photoimageable material and inhibit bleeding of the photoimageable material into the cavity from its inner edge. As a result, a semiconductor component can be flush mounted in the cavity with optimal thermal conductivity to the metal stiffener.

    摘要： The present invention is a persulfate etchant composition especially useful for dissolving copper during fabrication of microelectronic packages. The etchant is characterized by its ability to selectively etch copper in the presence of nickel, nickel-phosphorous and noble metal alloys therefrom. Furthermore, no deleterious galvanic etching occurs in this etchant-substrate system so that substantially no undercutting of the copper occurs. The combination of high selectivity and no undercutting allows for a simplification of the microelectronic fabrication process and significant improvements in the design features of the microelectronic package, in particular higher density circuits. The persulfate etchant composition is stabilized with acid and phosphate salts to provide a process that is stable, fast acting, environmentally acceptable, has high capacity, and can be performed at room temperature. A preferred etchant composition is 230 gm/liter sodium persulfate, 3 volume % phosphoric acid and 0.058 molar sodium phosphate dibasic.

    摘要： A circuitized substrate in which three conductive layers (e.g., electroplated copper foil) are bonded (e.g., laminated) to two dielectric layers. Each of the foil surfaces which physically bond to a respective dielectric layer are smooth (e.g., preferably by chemical processing) and may include a thin, organic layer thereon. One of the conductive layers may function as a ground or voltage (power) plane while the other two may function as signal planes with a plurality of individual signal lines as part thereof. An electrical assembly and an information handling system utilizing such a circuitized substrate are also provided, as is a method of making the substrate.
