Description

웨이퍼제조용 챔버의 잔류가스 집진장치{A Fume Collector}Residual gas dust collector in wafer manufacturing chamber {A Fume Collector}

본 발명은 웨이퍼를 처리할 때에 챔버(Chamber)의 내부에서 발생되는 오염물과 오염가스 등을 집진시켜 주도록 하고, 특히 챔버를 병렬로 설치하여 운용할 때에 각 챔버에서 압력강하가 발생되지 않고 균일한 상태를 유지할 수 있도록 된 웨이퍼제조용 챔버의 잔류가스 집진장치에 관한 것이다.The present invention collects contaminants and pollutants generated inside the chamber when processing a wafer, and in particular, the pressure drop does not occur in each chamber even when the chambers are installed in parallel and in a uniform state. The present invention relates to a residual gas dust collecting apparatus of a chamber for manufacturing a wafer.

이를 좀더 상세히 설명하면, 챔버의 외면에 루버히터를 설치하여 가스가 챔버의 내면에 증착되는 것을 방지하면서 가스의 활동력을 강화시켜 줄 수 있도록 하고, 메인공급라인을 통하여 질소(N2)가스를 챔버(Chamber)에 공급시킬 수 있도록 하되 메인공급라인에 레규레이터를 설치하여 정압의 질소가스를 균일하게 공급시켜 줄 수 있도록 하며, 메인공급라인과 배출라인과의 사이에 3개의 분배가지라인을 서로 연통되도록 병렬로 설치하여 두개의 분배가지라인은 벤트라인부로 사용하고 다른 하나는 퍼지라인부로 사용할 수 있도록 하여 설비구성을 심플하게 할 수 있도록 하며, 배출라인에는 필터장치와 히터블록를 구비하여 질소가스에 함유되어 있는 이물질을 필터링시킨 후에 가열에 의해 활동성을 강화시켜 챔버에 공급시킬 수 있도록 하며, 특히 복수개의 챔버를 병렬 운용할 때에 질소가스가 공급되는 메인공급라인에 분배고급라인을 연결하여 질소가스를 분배하여 각 챔버에 공급시킬 수 있도록 하되 각 분배공급라인에 레규레이터를 설치하여 정압의 질소가스를 공급시켜 상대적으로 압력강하가 발생되지 않도록 된 것이다.In more detail, by installing a louver heater on the outer surface of the chamber to prevent the gas is deposited on the inner surface of the chamber to enhance the active force of the gas, the nitrogen (N 2 ) gas through the main supply line chamber (Chamber) can be supplied, but regulator is installed in the main supply line to supply the nitrogen gas of constant pressure uniformly, and three distribution branch lines communicate with each other between the main supply line and the discharge line. It can be installed in parallel so that two distribution branch lines can be used as vent line part and the other can be used as purge line part to simplify the system configuration. The discharge line is equipped with filter device and heater block to be contained in nitrogen gas. After filtering foreign matters, it is possible to supply them to the chamber by enhancing the activity by heating. When several chambers are operated in parallel, the distribution advanced line can be connected to the main supply line where nitrogen gas is supplied so that the nitrogen gas can be distributed and supplied to each chamber. By supplying the relative pressure drop does not occur.

일반적으로 웨이퍼 반도체는 사진, 확산, 식각, 화학기상증착, 금속증착 등의 공정을 반복적으로 수행하여 반도체 칩으로 제조되어지는데, 이들 반도체 칩의 제조공정 중에서 확산, 식각, 화학기상증착 등의 공정은 밀폐공간으로 된 챔버(Chamber)의 내부에 필요한 가스를 공급하고 이와 같이 공급되는 공정가스가 웨이퍼 상에서 반응토록 하여 회로를 형성시키게 된다.Generally, wafer semiconductors are fabricated as semiconductor chips by repeatedly performing processes such as photographing, diffusion, etching, chemical vapor deposition, and metal deposition. Among the semiconductor chip manufacturing processes, processes such as diffusion, etching, and chemical vapor deposition are performed. The required gas is supplied to the inside of the chamber, which is a closed space, and the process gas thus supplied is allowed to react on the wafer to form a circuit.

상기와 같이 사용되는 각 공정가스는 대부분 독성이 매우 강할 뿐만 아니라 부식성이 강하여 챔버를 부식시키는 특성이 있으므로, 이러한 공정가스를 챔버의 내부에 방치하게 되면 챔버를 부식시켜 노화현상에 의해 수명을 현저하게 단축시키게 되고, 챔버의 내부에서 웨이퍼를 에칭 할 때에 발생되는 에칭가스의 부산물 및 미 반응 가스가 웨이퍼와 함께 배출되면서 챔버의 내부가 손상되며, 이를 다소나마 방지하기 위해서는 챔버의 내부를 주기적으로 클리닝(Cleaning)해주어야 하므로 생산성이 저하 될 뿐만 아니라 웨이퍼의 수율이 현저하게 떨어지면서도 오히려 설비의 운용비는 증가하게 되는 문제가 있었다.Each process gas used as described above is not only highly toxic but also highly corrosive to corrode the chamber. Therefore, when such a process gas is left inside the chamber, the chamber is corroded to prolong its life due to aging. As the by-product and unreacted gas of the etching gas generated when etching the wafer inside the chamber are discharged together with the wafer, the inside of the chamber is damaged, and the inside of the chamber is periodically cleaned to prevent this. Since the cleaning is required, not only the productivity is lowered, but the yield of the wafer is significantly lowered, but the operating cost of the equipment is increased.

더군다나, 웨이퍼를 에칭 할 때에 발생되는 에칭가스의 부산물 및 미 반응 가스가 별도의 정화과정 없이 외부로 배출될 경우에는 자연환경을 심각하게 오염시키고, 심지어 안전사고도 발생하게 되는 문제도 있었다.In addition, when the by-product and unreacted gas of the etching gas generated when etching the wafer is discharged to the outside without a separate purification process, there was a problem that serious pollution of the natural environment, even safety accidents occur.

도 4는 쳄버를 병렬로 설치하여 운용할 때에 종래의 잔류가스 집진장치의 벤트 및 퍼지장치부(40)를 보인 것이다.Figure 4 shows the vent and purge device portion 40 of the conventional residual gas dust collector when the chamber is installed and operated in parallel.

종래의 벤트 및 퍼지장치부(40)는, 질소가스메인공급라인(41)에 복수개의 분배고급라인(42)과 하나의 공급공유라인(44)이 병렬로 연결되어 공급되는 질소가스가 분배되어 공급되어지도록 되어 있고, 각 분배공급라인(42)에는 한 쌍의 분배가지라인(43-1)(43-2)이 연결되어 반도체제조용 챔버(1-1)와 연결된 배출라인(45)과 연결되어 있으며, 상기 분배가지라인(43-1)에는 스톱밸브(20)가 단독으로 설치되어 있고 다른 분배가지라인(43-2)에는 밸브(21)와 유량조절밸브(22)가 직렬로 연결되어 벤트부(47)를 형성하고 있으며, 상기 공유공급라인(44)은 배출분배라인(46)을 통하여 배출라인(45)과 각각 연결되어 있는데, 배출분배라인(46)에는 스톱밸브(49)가 설치되어 있고, 각 배출분배라인(46)에는 스톱밸브(24)와 유량조절밸브(23)가 공급 측에서 배출 측으로 직렬로 연결되어 퍼지부(48)를 형성하고 있다.In the conventional vent and purge device unit 40, a plurality of distribution advanced lines 42 and one supply sharing line 44 are connected in parallel to the nitrogen gas main supply line 41, and nitrogen gas is supplied and distributed. A pair of distribution branch lines 43-1 and 43-2 are connected to each distribution supply line 42 and connected to a discharge line 45 connected to the semiconductor manufacturing chamber 1-1. In the distribution branch line 43-1, a stop valve 20 is installed alone, and in another distribution branch line 43-2, a valve 21 and a flow control valve 22 are connected in series. The vent portion 47 is formed, and the shared supply line 44 is connected to the discharge line 45 through the discharge distribution line 46, respectively, and the stop valve 49 is provided at the discharge distribution line 46. Each discharge distribution line 46 has a stop valve 24 and a flow control valve 23 connected in series from the supply side to the discharge side. And forming a portion (48).

이와 같이 된 종래의 벤트 및 퍼지장치부(40)는 다음과 같은 문제가 단점으로 지적된다.As described above, the conventional vent and purge device 40 has the following problems as a disadvantage.

우선, 질소가스메인공급라인(41)에 복수개의 분배공급라인(42)과 하나의 공유공급라인(44)이 병렬로 연결되어 있고 상기 공유공급라인(44)에는 복수개의 배출분배라인(46)을 통하여 각 배출라인(45)과 연결되어 있으므로, 구조가 매우 복잡하였고, 제작도 용이하게 실시할 수 없는 문제가 있었다.First, a plurality of distribution supply lines 42 and one shared supply line 44 are connected to the nitrogen gas main supply line 41 in parallel, and the plurality of discharge distribution lines 46 are connected to the shared supply line 44. Since it is connected to each discharge line 45 through, the structure is very complicated, there was a problem that can not be easily performed.

또, 질소가스메인공급라인(41)에 병렬로 연결된 복수개의 분배공급라인(42)과 하나의 공유공급라인(44)에는 질소가스를 정압으로 공급시키도록 하는 장치가 설치되어 있지 않으므로 각 분배공급라인(42)과 공유공급라인(44)에 질소가스를 정압으로 공급시킬 수 없는 문제가 있었고, 어느 일 측의 분배공급라인(42)을 통하여 다량의 질소가스가 벤트부(47)에 공급되어지면 타 측의 분배공급라인(42)과 연결된 벤트부(47)에서는 압력강하가 심하게 발생하게 되는 문제가 있었으며, 이와 같이 압력강하가 발생된 벤트부(47)에서는 질소가스를 반도체제조용 챔버(1-1)에 순조롭게 공급시킬 수 없게 되므로 반도체제조용 챔버(1-1)의 기능이 약화되어 웨이퍼의 제조에 차질을 주게 되는 문제가 있었다.In addition, since a plurality of distribution supply lines 42 and one shared supply line 44 connected in parallel to the nitrogen gas main supply line 41 are not provided with a device for supplying nitrogen gas at a constant pressure, each distribution supply There was a problem that the nitrogen gas cannot be supplied to the line 42 and the common supply line 44 at a constant pressure, and a large amount of nitrogen gas is supplied to the vent part 47 through the distribution supply line 42 on one side. In the vent part 47 connected to the distribution supply line 42 on the other side of the ground, there was a problem in that the pressure drop was severely generated. In the vent part 47 in which the pressure drop occurred, nitrogen gas was introduced into the semiconductor manufacturing chamber 1. Since it is impossible to smoothly supply -1), there is a problem that the function of the semiconductor manufacturing chamber 1-1 is weakened, which hinders the manufacture of the wafer.

뿐만 아니라 각 배출라인(45)과 반도체제조용 챔버(1-1)에는 질소가스를 가열시켜 주는 장치가 구비되어 있지 않으므로 질소가스메인공급라인(41)을 통하여 유입되는 질소가스의 온도보다 배출라인(45)을 통하여 반도체제조용 챔버(1-1)로 공급되는 질소가스의 온도가 낮은 상태를 유지하게 되고, 반도체제조용 챔버(1-1)의 내부에서도 활동성이 저하되어 활발하게 운동을 할 수 없게 되므로 가스의 잔류시간이 감소하면서 기능이 약화될 뿐만 아니라 반도체제조용 챔버(1-1)의 내면과 부속품의 표면에 냉각된 질소가스가 증착되면서 부식성을 배가되어 수명을 현저하게 단축시키게 되는 문제가 있었다.In addition, each discharge line 45 and the semiconductor manufacturing chamber (1-1) is not equipped with a device for heating the nitrogen gas, so the discharge line (temperature of the nitrogen gas flowing through the nitrogen gas main supply line 41) The temperature of the nitrogen gas supplied to the semiconductor manufacturing chamber 1-1 through the 45 is maintained at a low state, and the activity of the nitrogen gas supplied to the semiconductor manufacturing chamber 1-1 is also lowered, thereby preventing active exercise. As the remaining time of the gas decreases, not only the function is impaired, but also cooling nitrogen gas is deposited on the inner surface of the semiconductor manufacturing chamber 1-1 and the surface of the accessory, thereby increasing the corrosiveness and shortening the service life significantly.

본 발명은 상기와 같은 문제를 해소할 수 있도록 더욱 개선된 웨이퍼제조용 챔버의 잔류가스 집진장치를 제공하려는 것이다.The present invention is to provide a residual gas dust collector of the wafer manufacturing chamber further improved to solve the above problems.

본 발명의 상기 및 기타 목적과 특징은 첨부도면에 의거한 다음의 상세한 설명에 의해 더욱 명확하게 이해 할 수 있을 것이다.The above and other objects and features of the present invention will be more clearly understood by the following detailed description based on the accompanying drawings.

첨부도면 도 1 내지 도 3은 본 발명에 따른 웨이퍼제조용 챔버의 잔류가스 집진장치의 구체적인 실현 예를 보인 것으로서, 도 1 및 도 2는 본 발명에 따른 웨이퍼제조용 챔버의 잔류가스 집진장치를 챔버에 설치한 상태를 보인 사시도 및 벤트 및 퍼지장치부(10)의 계통도이고, 도 3은 본 발명에 따른 웨이퍼제조용 챔버의 잔류가스 집진장치에 설치되는 히터블록를 보인 부분 단면사시도이다.1 to 3 show a specific implementation of the residual gas dust collecting apparatus of the wafer manufacturing chamber according to the present invention, Figures 1 and 2 are installed in the chamber the residual gas dust collecting apparatus of the wafer manufacturing chamber according to the present invention. 3 is a partial cross-sectional perspective view showing a heater block installed in a residual gas dust collecting apparatus of a wafer manufacturing chamber according to the present invention.

본 발명은 도 1에 예시된바와 같이 웨이퍼제조용 챔버(1)의 외면에 루버히터블록(4)를 설치하여 챔버 자체를 히팅시켜 줄 수 있도록 하였고, 외면에 도 1 및 도 2에 예시된바와 같은 벤트 및 퍼지장치부(10)를 설치하였다.The present invention is to install a louver heater block (4) on the outer surface of the wafer manufacturing chamber (1) as shown in Figure 1 to heat the chamber itself, as shown in Figures 1 and 2 on the outer surface The vent and purge unit 10 was installed.

상기 웨이퍼제조용 챔버(1)의 외면에 설치되는 루버히터블록(4)는 통상의 110V 또는 220V의 전원을 사용하여 40 ~ 60??의 설정온도로 챔버의 벽체를 가열시켜 내부의 잔류가스 및 수분(Fume)등의 물질을 가온시켜 주도록 하였다.The louver heater block 4 installed on the outer surface of the wafer manufacturing chamber 1 heats the walls of the chamber at a set temperature of 40 to 60 ° by using a normal 110V or 220V power supply, thereby remaining residual gas and moisture inside.
