    摘要： Certain organic polymeric materials are capable of reversibly accepting or donating electrons from a reducing entity. The redox sites in the polymer accept electrons and, as a result, a change in the properties of the polymer occurs. This change is useful in modifying or etching the polymeric material. The material can be modified by incorporation of metallic seeds into the material at a controlled depth. The seeds are incorporated by interaction of cations of the metals with the redox sites in the polymer, which cause the reduction of the cations to form the neutral metallic seeds. Subsequent exposure of the polymeric material containing the seeds to an electroless bath causes further deposition of metal having the desirable characteristic of good adhesion to the polymeric material. Etching of the polymeric material can be carried out as a result of an increase in solubility of the polymer in aprotic solvents when its redox sites have accepted electrons. The increased solubility allows openings to be etched in certain areas of the polymeric material that have been reduced, leaving other areas unchanged.

    摘要： This invention relates to three dimensional packaging of integrated circuit chips into stacks to form cuboid structures. Between adjacent chips in the stack, there is disposed an electrical interconnection means which is a first substrate having a plurality of conductors one end of which is electrically connected to chip contact locations and the other end of which extends to one side of the chip stack to form a plurality of pin-like electrical interconnection assemblies. The pin-like structures can be formed from projections of the first substrate having an electrical conductor on at least one side thereof extending from this side. Alternatively, the pin-like structures can be formed from conductors which cantilever from both sides of an edge of the first substrate and within which corresponding conductors from both sides are aligned and spaced apart by the first substrate thickness. The spaces contain solder and form solder loaded pin-like structures. The pin-like structures can be directly solder bonded to conductors on a second substrate surface or the pin-like structures can be adapted for insertion into apertures in a second substrate. The second substrate provides a means for electrically inter-connecting a plurality of these cuboids. Preferably, the first and second substrates are circuitized flexible polymeric films. The second substrate is disposed on a third substrate, such as a PC board, with a resilient material therebetween which permits a heat sink to be pressed into intimate contact with an opposite side of the cuboid structures.
