For the sake of understanding, the lift drive device of the present invention will be described in the same manner to the semiconductor fabrication equipment presented in the prior art. I would like to.

상기 도면에 도시된 바와 같이, 본 발명에 따른 반도체 제조설비용 웨이퍼 승강구동장치는, 진공챔버(10) 내에 마련된 웨이퍼 스테이지(11) 상의 웨이퍼(1)를 승강시켜주기 위한 리프트(12)가 구비되고, 상기 리프트(12)를 승강구동하기 위한 피스톤(21)을 수용하는 실린더(20)가 설치된 반도체 제조설비에 적용될 수 있다.As shown in the drawings, the wafer lift drive device for semiconductor manufacturing equipment according to the present invention includes a lift 12 for lifting the wafer 1 on the wafer stage 11 provided in the vacuum chamber 10. And a cylinder 20 for accommodating the piston 21 for elevating and driving the lift 12.

상기 실린더(20)는 피스톤(21)으로써 상기 리프트(12)와 연결되고, 상기 피스톤(21)의 승강구동시 진공챔버(10) 내의 기밀을 유지할 수 있도록 실린더(20)의 일부가 상기 진공챔버(10)의 내측으로 삽입된 상태를 유지하며 상기 진공챔버(10)에 고정 설치되어 있다. 이와 같이 진공챔버(10)에 실린더(20)가 고정된 일체형의 구조를 이루므로 상기 진공챔버(10)의 기밀을 유지하기 위한 오-링이 불필요하고, 리크포인트가 발생할 염려가 전혀 없게 된다.The cylinder 20 is connected to the lift 12 by a piston 21, and a portion of the cylinder 20 is maintained in the vacuum chamber 10 so as to maintain the airtightness in the vacuum chamber 10 when the piston 21 is driven up and down. 10) is fixed to the vacuum chamber 10 while being inserted into the inside. As such, since the cylinder 20 is fixed to the vacuum chamber 10, an o-ring for maintaining the airtightness of the vacuum chamber 10 is unnecessary, and there is no fear of leak points.

또한, 상기 실린더(20)의 내부에는 서로 다른 원형 복원성향을 갖는 형상기억합금재의 스프링이 복수개 내장되어 상기 피스톤(21)의 저면을 지지하고, 상기 스프링(22)(23)의 각 단부에는 각 스프링(22)(23)을 가열하기 위한 독립된 전원(24)(25)이 각각 연결되어 있다.In addition, a plurality of springs of shape memory alloy materials having different circular restoring tendencies are embedded in the cylinder 20 to support the bottom surface of the piston 21, and each end of the springs 22 and 23 may be Independent power sources 24 and 25 for heating the springs 22 and 23 are respectively connected.

이때, 상기 스프링은 팽창 상태의 원형 복원성향을 갖는 팽창용 스프링(22)과, 수축 상태의 원형 복원성향을 갖는 수축용 스프링(23)의 조합 구성으로 이루어지고, 상기 각 스프링(22)(23)은 동심의 형태로 중첩 배열된 것이다.At this time, the spring is made of a combination configuration of the expansion spring 22 having a circular restoring tendency of the expanded state, and the contracting spring 23 having a circular restoring tendency of the contracted state, each of the springs 22, 23 ) Are nested in concentric form.

한편, 형상기억합금(Shape-memory alloy)이란, 어떤 종류의 티탄-니켈합금이나 알루미늄합금 등으로 이루어진 금속재료를 고온에서 소성 변형시킨 후 그 재료의 고유 임계점 이상으로 가열하였을 때 나타나는 금속성을 이용한 것으로서, 실온에서 변형 후 재 가열하면 순간적으로 원래 성형시의 모양으로 복원되는 성질이 있는 합금을 일컫는다. 상기 형상기억합금은 전원(24)(25)을 차단한 후 외부의 힘이 작용하지 않으면 변형되지 않으므로 상승 및 하강 작동을 위한 별개의 팽창용 스프링(22)과 수축용 스프링(23)이 설치된다.Shape-memory alloy, on the other hand, is a metal-membrane alloy made of a certain kind of titanium-nickel alloy, aluminum alloy, etc., which is formed by plastic deformation at high temperature and heated above its critical point. In other words, it refers to an alloy that has the property of immediately re-heating after deformation at room temperature. The shape memory alloy is not deformed unless the external force is applied after the power supply 24, 25 is cut off, so that a separate expansion spring 22 and a contraction spring 23 are installed for the up and down operation. .

This occurs, and one of the springs 22 or 23 memorized at the temperature of the heat generated at this time expands or contracts and lifts the piston 21 and the lift 12. If the power supply 24 or 25 is cut off later, the initial state is restored.

본 발명에서는 팽창용 스프링(22)이 외측에 설치되고, 수축용 스프링(23)이 내측에 설치된 것으로 설정하였으나, 이에 한정됨 없이 그 외에 다양한 변형 배치가 가능하다. 상기 도면에 도시된 바에 의하면, 팽창용 스프링(22)과 연결된 전원(24)을 인가하였을 때는 상기 팽창용 스프링(22)이 신장됨으로써 피스톤(21)을 밀어올리게 되고(리프트 상승), 그 전원(24)이 차단되면 변형 전의 상태로 원위치되며, 상기 수축용 스프링(23)과 연결된 전원(25)을 인가하였을 때는 상기 수축용 스프링(23)이 수축됨으로써 피스톤(21)을 끌어내리게 되고(리프트 하강), 그 전원(25)이 차단되면 변형 전의 상태로 원위치된다.In the present invention, the expansion spring 22 is installed on the outside, the contraction spring 23 is set to be installed on the inside, but is not limited to this various other various arrangements are possible. As shown in the figure, when the power supply 24 connected to the expansion spring 22 is applied, the expansion spring 22 is extended to push up the piston 21 (lift lift), and the power supply ( When the 24 is blocked, it is returned to its original state before deformation. When the power source 25 connected to the contracting spring 23 is applied, the contracting spring 23 is contracted to pull down the piston 21 (lift lowering). When the power source 25 is cut off, it is returned to the state before deformation.

상기 팽창용 스프링(22) 및 수축용 스프링(23)은 이들 중 어느 한쪽에 변형이 진행될 때 다른 한쪽의 탄성을 극복할 수 있는 정도의 여력을 갖는 것이다.The expansion spring 22 and the contraction spring 23 has a sufficient amount of room to overcome the elasticity of the other side when the deformation to any one of them.

이상에서 기술한 바와 같은 본 발명에 따른 반도체 제조설비용 웨이퍼 승강구동장치에 의하면, 금속 자체의 원형 복원력을 이용한 실린더를 사용함으로써 주변장치가 불필요하여 장치의 단순화를 실현할 수 있고, 고장률이 적으며, 리크포인트를 최소화할 수 있게 되는 효과를 갖는다.According to the wafer lift drive device for semiconductor manufacturing equipment according to the present invention as described above, by using the cylinder using the circular restoring force of the metal itself, the peripheral device is unnecessary, so that the device can be simplified and the failure rate is low.
