Patent ID: 7658890

Claim:
A perfluoride processing apparatus comprising; a semiconductor fabrication factory building having an inner portion; a clean room having an inner portion disposed in said inner portion of said semiconductor fabrication factory building; a plurality of semiconductor fabrication apparatuses disposed in said inner portion of said clean room; an exhaust gas pipe connected to said plurality of semiconductor fabrication apparatuses in said inner portion of said clean room with perfluoride supplied thereto for permitting a flow of a perfluoride exhaust gas therein; a perfluoride decomposition device disposed outside said semiconductor fabrication factory building and said clean room, and connected to said exhaust gas pipe for decomposing said perfluoride contained in said exhaust gas; whereby said exhaust gas pipe extends from said clean room, through said semiconductor fabrication factory building to said perfluoride decomposition device disposed outside said semiconductor fabrication factory building, said perfluoride in said exhaust gas is conveyed out of the inner portions of said clean room and semiconductor fabrication factory building to the outside of said semiconductor fabrication factory building, and exhaust gas is conveyed to said perfluoride decomposition device through said exhaust gas pipe.
