ABSTRACT:
A wafer-scale probe card for temporary electrical contact to a sample wafer or other device, for burn-in and test. The card includes a plurality of directly metallized single-walled or multi-walled nanotubes contacting a pre-arranged electrical contact pattern on the probe card substrate. The nanotubes are arranged into bundles for forming electrical contacts between areas of the device under test and the probe card. The bundles are compressible along their length to allow a compressive force to be used for contacting the probe card substrate to the device under test. A strengthening material may be disposed around and/or infiltrate the bundles. The nanotubes forming the bundles may be patterned to provide a pre-determined bundle profile. Tips of the bundles may be metallized with a conductive material to form a conformal coating on the bundles; or metallized with a conductive material to form a continuous, single contact surface.
