Abstract
Disclosed is a process stop loss reduction system, in which in case that pressure in a trapping apparatus and pressure in a process chamber are increased because of space clogging or the like caused by reaction by-products while the trapping apparatus for trapping of a reaction by-product contained in exhaust gas discharged from the process chamber operates over a long period of time during a semiconductor process, only the trapping apparatus, to which a supply of exhaust gas is cut off, may be quickly replaced while inert gas is received in an idle state and continuously supplied to a vacuum pump through a bypass pipe of the trapping apparatus without stopping an operation of (shutting down) a semiconductor manufacturing process chamber facility, and then the trapping apparatus may be supplied with the exhaust gas again.
