Abstract:
1. A method for verifying a test substrate ( 7 ) in a prober under defined thermal conditions, wherein the prober has a housing having at least two housing sections, in one housing section of which, designated hereinafter as test chamber ( 2 ), the test substrate ( 7 ) to be verified is held by a chuck ( 5 ) and is set to a defined temperature, and in the other housing section of which, designated hereinafter as probe chamber ( 3 ), probes ( 23 ) are held by virtue of the test substrate ( 7 ) and the probes ( 23 ) being positioned relative to one another by means of at least one positioning device and the probes ( 23 ) subsequently making contact with the test substrate ( 7 ) for verification purposes, characterized in that the probes ( 23 ) are set to a temperature that is independent of the temperature of the test substrate ( 7 ) by means of a temperature-regulated gas flow ( 11 ) that flows through the probe chamber ( 3 ), and this probe temperature is maintained.
