    摘要: A method for forming three-dimensional circuitization in a substrate is provided for forming conductive traces and via contacts. In the method, a substrate formed of a substantially insulating material is first provided, grooves and apertures in a top surface of and through the substrate are then formed, followed by filling the grooves and apertures with an electrically conductive material such as a solder. The method can be carried out at a low cost to produce high quality circuit substrates by utilizing an injection molded solder technique or a molten solder screening technique to fill the grooves and the apertures. The grooves and the apertures in the substrate may be formed by a variety of techniques such as chemical etching, physical machining and hot stamping.

    摘要: This discloses a probe structure which does not rely on cantilevered wire and which has improved and controlled contact pressure between the probe tip contacts and the I/O pads on a semiconductor chip and which comprises a plurality of conductive contact electrodes, electrically coupled to respective leads, formed on a film stretched across a respective plurality of through holes established in a substrate. The through holes and the contact electrodes are aligned with one another and both positionally match selected I/O pads existing on a semiconductor chip to be probed. Also disclosed is a probe utilizing means connected to each one of the holes to control the pressure in the holes and between the probes and any contact on a device in contact with the probe.
