Claim 10:
11. A semiconductor test device comprising:
a plurality of test pairs, each test pair having a test board and a temperature control module arranged inside a temperature controlled chamber having an air inlet and an air outlet,
wherein each test board includes a plurality of semiconductor devices arranged in a matrix arrangement on a surface of the test board;
wherein in each test pair the temperature control module controls the temperature of the air applied to a corresponding one of the test boards to a target temperature which is the same for all the test boards regardless of their location within the chamber, and
the temperature control module comprises:
an upper region including inflow units configured to introduce the air into the chamber;
a middle region configured to mix the air introduced by the inflow units; and
a lower region including outflow units configured to apply the mixed air to the semiconductor devices on the test board.
