Detailed Specs

The liquid metal Mercury is used to form temporary electrical contacts at four terminals. These probes cause no damage to the sample and permit no contact pressure probing.

The system meets the requirements for ultra shallow junction probing, but may well be applied to other ultra thin films found for example in hard disks and flat panels.

Advantages of Mercury Probes:

Non destructive probing
No pressure probing
Highly repeatable contact area
Basic features:

Safe design principle
Refreshed mercury before each contact insures clean contact
Clean and safe Mercury handling
Mercury reservoir replacement only twice a year
