When using a cryogenic probe station, wafer mounting methodologies are a key element of wafer-level characterization. The mounting materials and approach will influence device temperature, sample exchange time, and even the ability to post process a wafer after characterization.
To learn more about the mounting methods commonly used in cryogenic probe stations, download our new app note, “Wafer Mounting in a Lake Shore Cryogenic Probe Station.” It discusses in detail the methods while listing advantages and disadvantages for each, including:
- GE varnish
- Vacuum grease and clamping
- Electrically conductive silver paint, silver paste, or carbon paste compounds
- Cyanoacrylate adhesives.
