Patent ID: 7069984

Claim:
A temperature control system for a semiconductor processing facility comprising: a cooling unit for controlling the temperature of a cooling fluid; and a plurality of remote temperature control modules in fluid communication with said cooling unit, each of said remote temperature control modules including: a cooling fluid circulation loop for circulating said cooling fluid through said remote temperature control module, said cooling fluid circulation loop being in fluid communication with said cooling unit; a heat transfer fluid circulation loop for circulating a heat transfer fluid through said remote temperature control module, said heat transfer fluid being in fluid communication with at least one process component of said semiconductor processing facility; an integrated heat exchanger including a portion of the cooling fluid circulation loop, a portion of the heat transfer fluid circulation loop and an electrical heat source, the integrated heat exchanger exchanging heat between said cooling fluid that is circulated in said cooling fluid circulation loop and said heat transfer fluid that is circulated in said heat transfer fluid circulation loop, a cooling fluid control valve in fluid communication with said cooling fluid circulation loop for controlling the circulation of said cooling fluid through said cooling fluid circulation loop; and a controller programmed with a temperature control logic for controlling said cooling fluid valve and controlling said current controller.
