What is a cryogenic probe station?
A cryogenic probe station enables non-destructive testing of materials or devices in a cryogen-refrigerated vacuum chamber, with electrically conducting probes used on wafer samples to measure material phenomena as a function of temperature (as well as magnetic field on some models).
