Abstract:
1. A gas supplying system for supplying a processing gas to a processing apparatus, comprising: a processing gas supply source for supplying the processing gas; a gas supply pipe for supplying the processing gas from the processing gas supply source into the processing apparatus; a nonreactive gas supply source for supplying a nonreactive gas into the gas supply pipe; a vacuum evacuation unit for evacuating the inside of the gas supply pipe to vacuum; and a control unit for receiving a signal from the processing apparatus and controlling an inner state of the gas supply pipe in response to the received signal, wherein the control unit keeps the gas supply pipe charged with the nonreactive gas to be in a standby state while the system is in operation; the control unit exhausts, if a processing gas use start signal is received from the processing apparatus, the nonreactive gas from the gas supply pipe to create a vacuum therein by the vacuum evacuation unit, charges the gas supply pipe with the processing gas, and starts a supply of the processing gas from the processing gas supply source; and the control unit stops, if a processing gas use finish signal is received from the processing apparatus, the supply of the processing gas from the processing gas supply source, exhausts the processing gas from the gas supply pipe to create a vacuum therein by the vacuum evacuation unit, and charges the gas supply pipe with the nonreactive gas.
