도 1은 예시적인 실시예에 따른 웨이퍼 이송 장치를 구비하는 증착 설비를 나타내는 개략 구성도이고, 도 2는 도 1의 A부를 나타내는 단면도이고, 도 3은 홀더는 나타내는 사시도이다.Fig. 1 is a schematic configuration diagram showing a deposition facility having a wafer transfer apparatus according to an exemplary embodiment, Fig. 2 is a cross-sectional view showing part A of Fig. 1, and Fig. 3 is a perspective view showing a holder.

도 1 내지 도 3을 참조하면, 예시적인 실시예에 따른 증착 장치(100)는 일예로서, 챔버(120), 히터(130), 웨이퍼 이송부(140), 적층 방지 부재(150), 홀더(160) 및 와셔(170)를 포함한다.1 to 3 , a deposition apparatus 100 according to an exemplary embodiment is, as an example, a chamber 120 , a heater 130 , a wafer transfer unit 140 , an anti-stacking member 150 , and a holder 160 . ) and a washer 170 .

한편, 챔버(120)는 내부 공간을 가지며, 복수개의 히터(130)가 챔버(120)의 내부 공간에 설치된다. 일예로서, 히터(130)는 챔버(120)에 4개가 상호 이격 배치되도록 구비될 수 있다. 그리고, 히터(130)는 대략 웨이퍼의 형상에 대응되는 형상을 가질 수 있다. 한편, 챔버(120)의 측면에는 웨이퍼(W)가 공급되는 웨이퍼 이송구(122)가 구비될 수 있다. 웨이퍼 이송구(122)를 통해 챔버(120)로 공급된 웨이퍼는 복수개의 히터(130) 중 어느 하나에 안착된다.Meanwhile, the chamber 120 has an internal space, and a plurality of heaters 130 are installed in the internal space of the chamber 120 . As an example, four heaters 130 may be provided in the chamber 120 to be spaced apart from each other. In addition, the heater 130 may have a shape substantially corresponding to the shape of the wafer. On the other hand, the side of the chamber 120 may be provided with a wafer transfer port 122 to which the wafer (W) is supplied. The wafer supplied to the chamber 120 through the wafer transfer port 122 is seated on any one of the plurality of heaters 130 .

그리고, 공정 진행 시 웨이퍼(W)는 히터(130)의 상부에 안착된다. 또한, 웨이퍼(W)의 이송 시 웨이퍼(W)는 홀더(160)에 안착된 상태에서 웨이퍼 이송부(140)에 의해 승강 및 회전된다.In addition, during the process, the wafer W is seated on the heater 130 . In addition, when the wafer W is transferred, the wafer W is lifted and rotated by the wafer transfer unit 140 while seated on the holder 160 .

히터(130)는 대략 원형의 플레이트 형상을 가지며 웨이퍼(미도시)를 가열할 수 있도록 웨이퍼보다 큰 크기를 가질 수 있다. 한편, 히터(130)는 상기한 바와 같이 챔버(120)에 4개가 원주 방향을 따라 상호 이격 배치될 수 있다. 그리고, 히터(130)는 챔버(120)에 고정 설치될 수 있다. 일예로서, 히터(130)에는 원주 방향을 따라 복수개의 설치홈(132, 도 2 참조)이 구비될 수 있다. 설치홈(132)에는 후술할 적층 방지 부재(150)의 연장부(152)와 홀더(160)가 삽입 배치될 수 있다. 다시 말해, 증착 공정의 진행 시 설치홈(132)에는 연장부(152)와 홀더(160)가 삽입 배치된다. 그리고, 웨이퍼 이송부(140)가 상승하는 경우 연장부(152)와 홀더(160)는 설치홈(132)으로부터 상부측으로 이동되어 설치홈(132)으로부터 이탈된다.The heater 130 has a substantially circular plate shape and may have a size larger than a wafer to heat a wafer (not shown). Meanwhile, four heaters 130 may be disposed to be spaced apart from each other in the circumferential direction in the chamber 120 as described above. In addition, the heater 130 may be fixedly installed in the chamber 120 . As an example, the heater 130 may be provided with a plurality of installation grooves 132 (refer to FIG. 2 ) along the circumferential direction. An extension part 152 and a holder 160 of the anti-stacking member 150 to be described later may be inserted into the installation groove 132 . In other words, the extension part 152 and the holder 160 are inserted into the installation groove 132 during the deposition process. In addition, when the wafer transfer unit 140 rises, the extension 152 and the holder 160 move upward from the installation groove 132 to separate from the installation groove 132 .

여기서, 원주 방향이라고 하면 챔버(120)의 외주면과 히터(130)의 외주면을 따라 회전되는 방향을 의미한다.Here, the circumferential direction means a direction of rotation along the outer circumferential surface of the chamber 120 and the outer circumferential surface of the heater 130 .

웨이퍼 이송부(140)는 복수개의 히터(130)의 주위에 배치되며 히터(130)를 감싸도록 배치될 수 있다. 다시 말해, 웨이퍼 이송부(140)는 히터(130)를 제외한 영역에 배치되는 형상을 가질 수 있다. 한편, 웨이퍼 이송부(140)는 챔버(120)에 승강 및 회전 가능하게 설치될 수 있다. 즉, 히터(130)에 안착된 웨이퍼(W)를 상승 및 회전시키도록 웨이퍼 이송부(140)는 챔버(120)에 승강 및 회전 가능하게 설치될 수 있다. 한편, 웨이퍼 이송부(140)는 챔버(120)의 이동축(124)에 설치되어 이동축(124)과 함께 승강 및 회전될 수 있다.The wafer transfer unit 140 may be disposed around the plurality of heaters 130 and may be disposed to surround the heaters 130 . In other words, the wafer transfer unit 140 may have a shape disposed in an area excluding the heater 130 . On the other hand, the wafer transfer unit 140 may be installed in the chamber 120 to be lifted and rotatable. That is, the wafer transfer unit 140 may be rotatably installed in the chamber 120 to lift and rotate the wafer W seated on the heater 130 . Meanwhile, the wafer transfer unit 140 is installed on the moving shaft 124 of the chamber 120 to be lifted and rotated together with the moving shaft 124 .

적층 방지 부재(150)는 웨이퍼 이송부(140)에 설치되며 대략 히터(130)의 주위를 감싸는 원형의 고리 형상을 가질 수 있다. 한편, 적층 방지 부재(150)에는 히터(130)의 설치홈(132)에 삽입되도록 하부로 연장 형성되는 연장부(152)가 구비될 수 있다. 그리고, 연장부(152)에는 홀더(160)와의 조립을 위한 나사산(152a)이 구비될 수 있다. 일예로서, 적층 방지 부재(150)는 세라믹 재질로 이루어질 수 있다.The anti-stacking member 150 is installed on the wafer transfer unit 140 and may have a circular annular shape substantially surrounding the heater 130 . On the other hand, the anti-stacking member 150 may be provided with an extension portion 152 extending downwardly to be inserted into the installation groove 132 of the heater 130 . In addition, the extension 152 may be provided with a screw thread 152a for assembling with the holder 160 . As an example, the anti-stacking member 150 may be made of a ceramic material.
