Abstract:
The combination of a semiconductor device fabrication facility and a thermoelectric-cooling temperature control apparatus for controlling a temperature condition established in the facility during a process of fabricating a semiconductor device, wherein said semiconductor fabrication facility has a processing chamber, and a semiconductor wafer support disposed in the processing chamber for supporting a wafer to be processed, and said temperature control apparatus comprises a heat exchanger disposed in a heat exchange relationship with said wafer support, the heat exchanger comprising a thermoelectric cooling element including two dissimilar electrical conductors in contact with each other, and a power source connected to said conductors so as to supply electric current therethrough, whereby a Peltier Effect is produced which causes the thermoelectric element to absorb and radiate heat according to the amount of current flowing through parts of the conductors in contact with each other.
