摘要

Wafer probes for aluminum pads with 110GHz performance and low repeatable contact resistance are demonstrated. These probes are based on an existing membrane probe card technology that routinely achieves less than 0.2 ohms contact resistance in production environments. We demonstrate a ground-signal-ground (GSG) probe with less than 0.1 ohms contact resistance over 5000 contact cycles and less than 0.05 ohms variation during a 5-hour single-contact test interval, both on aluminum pads. 1.8dB maximum attenuation and 12dB minimum return losses at both the coaxial connector and the probe tips are achieved from 0 to 110GHz.
