Abstract:
1. A probe card assembly for providing electrical interconnection between a semiconductor device to be tested and a test system, the probe card assembly comprising: a plurality of probes supported by a support substrate, each of the plurality of probes including an end portion extending away from the support substrate, the end portion being configured to be electrically connected to a semiconductor device to be tested; a dielectric sheet positioned between the support substrate and the end portion of the plurality of probes such that the probes extend through apertures defined by the dielectric sheet, wherein one or more of the apertures are dimensioned such that one or more of the plurality of probes extend through and do not contact the dielectric sheet adjacent a respective aperture when the probe card assembly is in a test position with respect to the semiconductor device to be tested; and an electrically conductive layer disposed on the dielectric sheet, the electrically conductive layer being spaced from the apertures.
