Methods for compensating for a test temperature deviation

A method for compensating for a test temperature deviation in a semiconductor device handler having a cooling fluid supplying apparatus, a nozzle assembly configured to spray cooling fluid supplied from the cooling fluid supplying apparatus onto at least one semiconductor device, respectively, fitted to at least one test socket, and a control unit configured to control the cooling fluid supplying apparatus, the method comprising:

• fitting at least one semiconductor device to at least one test socket and starting a test;
• measuring in real time a temperature change of the semiconductor device;
• comparing the temperature change to a preset value;
• spraying cooling fluid onto the semiconductor device if the measured change is higher than a preset value as a result of the comparison, wherein spraying the cooling fluid comprises controlling the cooling fluid supplying apparatus before fitting the semiconductor device to the test socket, and determining if the cooling fluid is in a gas state based on a measured temperature change rate before starting the test;
• and
• stopping spray of the cooling fluid onto the semiconductor device if the measured temperature change is below the preset value as the result of the comparison.
