An exposure system is provided which can maintain a predetermined
performance of the exposure apparatus stably by maintaining a cooling
capacity by preventing a negative pressure from being generated in a
circulation path of the liquid and preventing the back pressure from
increasing even if at least a part of a temperature adjusting device is
disposed under a disposition surface of the exposure apparatus due to the
disposition area. A sealed tank which stores the cooling agent which is
circulated in the circuiting systems and a pump, etc., which circulates
the cooling agent are disposed under the disposition surface FL of the
exposure system. The reticle stage and the wafer stage which are objects
of which the temperature is supposed to be controlled are disposed above
the disposition surface FL. A tank which open to air is provided so as to
prevent the negative pressure from being generated in the reticle stage,
etc. such that the tank and the tank are connected by a connecting piping
arrangement. Also, the piping arrangement which eliminates the bubbles
which are contained in the cooling agent which is circulated in the
circulating systems are connected to the circulating systems.
