Abstract

Probe systems and methods including active environmental control are disclosed herein. The methods include placing a substrate, which includes a device under test (DUT), on a support surface of a chuck. The support surface extends within a measurement environment that is at least partially surrounded by a measurement chamber. The methods further include determining a variable associated with a moisture content of the measurement environment and receiving a temperature associated with the measurement environment. The methods also include supplying a purge gas stream to the measurement chamber at a purge gas flow rate and selectively varying the purge gas flow rate such that a dew point temperature of the measurement environment is within a target dew point temperature range. The methods further include providing a test signal to the DUT and receiving a resultant signal from the DUT. The systems include probe systems that perform the methods.
