主权项 1. A method for implementing low temperature wafer testing of a completed wafer comprising: applying a coolant gel to the completed wafer, said coolant gel being electrically insulating and hydrophobic; cooling the gel coated wafer in a temperature range including −40° C. or −55° C.; applying one or more electrical test probes through the gel to electrical contacts of the cooled wafer, said coolant gel eliminating condensation on the electrical contacts, and performing testing of the cooled wafer.
