Abstract

Probe cards are configured with protective circuitry suitable for use in electrical testing of semiconductor dice without damage to the probe cards. Protective fuses are provided in electrical communication with conductive traces and probe elements (e.g., probe needles) of a probe card. The fuses may be active or passive fuses, and are preferably self-resetting, repairable, and/or replaceable. Typically, the fuses will be interposed in, or located adjacent to, conductive traces residing over a surface of the probe card. Methods of fabricating a probe card are provided, as well as various probe card configurations. A semiconductor die testing system using the probe card is also provided.
