Mercury Probes
Mercury Probes MDC MERCURY PROBES are precision instruments that enable rapid, convenient, and non-destructive measurements of semiconductor samples by probing wafers with mercury to form contacts of well-defined area.

MDC MERCURY PROBES may be connected to C-V plotters, computerized semiconductor measurement systems, curve tracers, or doping profilers for a variety of measurements. MERCURY PROBES eliminate time consuming metallization and their convenience make them ideal tools for production process monitoring applications. Their accuracy and reproducibility make them attractive for R&D applications.

There are 2 types of Mercury Probes available. Standard and Mapping versions. All MDC Mercury Probes have 3 function contacts with the unique MDC dot-ring configuration. This allows contact to be made in both front-back and front-front modes allowing for measurements on semi-insulating substrates. Also, a guard ring can be configured.

The standard probes come in 3 sizes. 3", 6", and 8" diameters. The Mapping Mercury Probe allows for repeatable contacts over a wafer using X and Y controls. Mapping Mercury Probes come 8" and 12" diameters.

Nominal contact diameter is 760 microns.

Special diameter platforms or contact areas are available.
