Abstract: An electronic package (10) including a first circuitized substrate 11 (e.g., printed circuit board) having connected thereto a second, flexible circuitized substrate (e.g., polyimide with chrome-copper-chrome circuitry thereon). The second substrate is in turn electrically connected to the invention's semiconductor device (e.g., silicon chip), which device in turn is attached to a heat spreader (37) for providing effective heat transference from the device to the package's heat sink (33). The heat sink is attached to the first substrate (e.g., using solder). Significantly, the coefficient of thermal expansion of the heat spreader, semiconductor device and adhesive used to connect same are substantially similar in order to provide an effective heat path from the heat-generating device to the corresponding, much larger heat sink.

Abstract: A catalyst solution for making surfaces receptive to the deposition of adherent electroless metal layers includes a complex of a precious metal salt with dimethyl sulfoxide such as, for example, Pd Cl2 . 2(CH3)2 SO together with a group IV metal salt such as, for example, stannous chloride. A process for rendering surfaces, such as glass, receptive to adherent electroless metal layers using the catalyst solution is also provided.

Abstract: METHOD AND APPARATUS FOR TESTING OF INTEGRATED CIRCUIT CHIPS A method of testing semi-conductor chips is disclosed. The individual semiconductor chips have I/O, power, and ground contacts. In the method of the invention a chip test fixture system is provided. The chip test fixture system has contacts corresponding to the contacts on the semiconductor chip. The carrier contacts have dendritic surfaces. The chip contacts are brought into electrically conductive contact with the conductor pads on the chip test fixture system. Test signal input vectors are applied to the inputs of the semiconductor chip, and output signal vectors are recovered from the semiconductor chip. After testing the chip is removed from the substrate.

Abstract: Processes are provided for improving the surface properties of polyimide articles, especially of those polyimide articles which contain significant amounts of transimide. The surface of the polyimide is first treated with a base to convert the surface layer of both the polyimides and the transimides to the polyamic salt. Thereafter the surface layer of the converted polyamic salt is treated with an acid to convert the layer to a polyamic acid. This is followed by a cure preferably in infrared radiation at a sufficiently rapid rate to prevent the formation of any significant amounts of transimide and provide only polyimide. Following this treatment metallization is applied to the improved surface layer.

Abstract: The article comprises a polyimide layer and a layer of a metal benzotriazole above said polyimide layer wherein said metal is selected from the group of copper, silver, and gold, and a layer of metal adjoining said metal benzotriazole layer. The method for forming such an article comprises the steps: providing a layer of a metal benzotriazole adjoining a polyamic acid layer that may be a layer of a polyimide substrate being converted to polyamic acid, wherein said metal is selected from the group of copper, silver and gold; providing a layer of metal adjoining said layer of metal benzotriazole and converting said polyamic acid to polyimide.
