At this time, in order to remove the reaction gas remaining in the reaction gas supply line, nitrogen gas supplied from a nitrogen gas supply source is reacted Gas supply line.

제1도는 종래의 반도체설비의 가스배기라인을 나타내는 모식도이다.FIG. 1 is a schematic view showing a gas exhaust line of a conventional semiconductor facility.

제1도를 참조하면, 가스봄베(Gas bombe : 10) 내부의 가스실린더(12)에서 공급되는 반응가스는 밸브(14, 16)를 통과하여 가스봄베(10) 외부의 공정챔버(18)에 공급되어 반도체 소자 제조공정이 이루어지도록 되어 있다.1, a reaction gas supplied from a gas cylinder 12 in a gas bomb 10 passes through valves 14 and 16 and is supplied to a process chamber 18 outside the gas cylinder 10 So that the semiconductor device manufacturing process is performed.

연속적인 반도체 소자 제조공정과정에 가스실린더(12)의 반응가스가 모두 소모되면, 반응가스 공급라인에 위치한 밸브(14, 16)를 닫고 가스봄베(10) 외부의 질소가스공급원(20)에서 공급되는 질소가스가 밸브(22, 24)를 통과하여 배기라인 유입부(26)로 공급되도록 되어 있다.When the reaction gas of the gas cylinder 12 is exhausted during the continuous semiconductor device manufacturing process, the valves 14 and 16 located in the reaction gas supply line are closed and supplied from the nitrogen gas supply source 20 outside the gas cylinder 10 Nitrogen gas is supplied to the exhaust line inflow portion 26 through the valves 22,

배기라인 유입부(26)를 통과한 질소가스는 고무재질로, 내부 및 외부에 주름이 형성되고, 가스봄베(10) 외부에 위치한 배기라인(28)을 통하여 산배기 덕트(30)로 공급되어 외부로 방출되도록 되어 있다.The nitrogen gas that has passed through the exhaust line inflow section 26 is made of a rubber material and is corrugated on the inside and the outside and supplied to the acid exhaust duct 30 through the exhaust line 28 located outside the gas cylinder 10 And is discharged to the outside.

상기 배기라인(28)과 배기라인 유입부(26) 그리고 배기라인(28)과 배기덕트(30)는 일반테이프로 밀봉결합되어 있다.The exhaust line 28, the exhaust line inlet 26, the exhaust line 28, and the exhaust duct 30 are sealed to each other by a general tape.
