  • Semiconductor thermal conditioning apparatus and method
    Patent number: 5966940
    Abstract: An apparatus for thermally conditioning a semiconductor unit is provided which includes a surface plate for receiving the semiconductor unit thereon which is connected to a thermoelectric device and a closed loop heat exchanger. At least one temperature sensor is disposed adjacent the surface plate for sensing the temperature of the surface plate. The thermoelectric device has first and second sides with the first side disposed against the surface plate. The closed loop heat exchanger is coupled to the second side of the thermoelectric device. The closed loop heat exchanger includes a chamber or cavity having an inlet and an outlet with the chamber disposed adjacent the second side of the thermoelectric device. The closed loop heat exchanger further includes conduit connected to the inlet and outlet of the chamber and a heat transfer unit connected to the conduit opposite the chamber.
