Description

반도체 식각장치의 결합형 실리콘 링Bonded silicon ring of semiconductor etching device
본 발명은 반도체 식각장치의 결합형 실리콘 링에 관한 것으로서, 보다 상세하게는 실리콘 링을 상,하 및 외부로 분리하고 조립하게 되어 실제 소모가 되는 부품만 교체하여 사용할 수 있는 반도체 식각장치의 결합형 실리콘 링에 관한 것이다.The present invention relates to a bonded silicon ring of a semiconductor etching apparatus, and more particularly, a bonded type of a semiconductor etching apparatus that can be used by replacing only parts that are actually consumed by separating and assembling the silicon ring upward, downward, and externally. It relates to a silicone ring.
일반적으로 반도체 소자는 반도체 기판(즉, 실리콘 웨이퍼)상에 반도체성 박막, 도전성 박막 또는 절연성의 박막을 형성하고, 이들의 일부를 식각하여 제작한다.In general, semiconductor devices are fabricated by forming a semiconductor thin film, a conductive thin film, or an insulating thin film on a semiconductor substrate (ie, a silicon wafer), and etching a part of them.
최근 들어, 박막의 형성 공정과 식각 공정시 플라즈마 기술을 이용하여 공정 효율을 증대시키고 있다.Recently, plasma technology has been used to increase process efficiency during thin film formation and etching processes.
식각 공정을 예를 들면, 플라즈마 식각 챔버에 반응 가스를 공급하고, 챔버에 고주파 전원을 인가하여 반응 가스를 여기된 플라즈마 상태가 되도록 한다.In the etching process, for example, a reactive gas is supplied to a plasma etching chamber, and a high frequency power is applied to the chamber to cause the reactive gas to become an excited plasma state.
이와 같이, 반응 가스를 플라즈마화시켜 웨이퍼 상의 박막들과의 반응성을 높일 뿐만 아니라, 플라즈마화된 반응 가스의 물리적인 충돌에 의해 박막이 제거됨으로 인해 박막의 제거 성능을 향상시킬 수 있다.In this way, not only the reactivity with the thin films on the wafer is increased by converting the reactive gas into plasma, but also the removal performance of the thin film can be improved because the thin film is removed by physical collision of the plasmaized reactive gas.
플라즈마 처리 장치의 경우 웨이퍼 상부에 형성되는 플라즈마의 분포가 균일하게 유지되어야 하는 문제가 있다.In the case of the plasma processing apparatus, there is a problem that the distribution of plasma formed on the wafer must be uniformly maintained.
따라서, 웨이퍼의 가장자리 부위에 원형의 링을 배치시켜 웨이퍼 상의 플라즈마 분포의 균일도를 향상시켰다.Therefore, the uniformity of plasma distribution on the wafer was improved by placing a circular ring at the edge of the wafer.
즉, 플라즈마를 웨이퍼의 외측까지 확대시켜 웨이퍼 상측의 플라즈마 균일도를 향상시킬 수 있었다.In other words, the plasma uniformity on the upper side of the wafer could be improved by expanding the plasma to the outside of the wafer.
종래의 실리콘 링의 제조를 간략히 살펴보면 다음과 같다.A brief look at the manufacture of a conventional silicon ring is as follows.
와이어 소잉(sawing) 공정을 통해 절단된 실리콘 원판을 마련한다. 실리콘 원판에 관통홀을 형성하는 코어링 공정을 수행하여 실리콘 링 몸체를 형성한다. 코어링 된 실리콘 링 몸체는 연삭기 또는 MCT를 이용하여 내경 및 외경을 가공하여 실리콘 링을 형성한다. 그리고, 실리콘 링의 표면 평탄화를 위해 로터리 연삭기를 이용하여 실리콘 링의 표면 및 이면을 그라인딩한다.A silicon disc cut through a wire sawing process is prepared. A silicon ring body is formed by performing a coring process of forming a through hole in the silicon disk. The cored silicone ring body forms a silicone ring by processing the inner and outer diameters using a grinding machine or MCT. Then, to planarize the surface of the silicon ring, the surface and the back surface of the silicon ring are ground using a rotary grinder.
그라인딩 후의 폴리싱은 왁스 공정을 사용하는 매엽식 단면 폴리싱이므로 실리콘 링 표면의 평탄도가 나쁘며, 생산성이 저하되는 문제가 발생한다. 또한, 실리콘 링의 표면이 고르지 못하기 때문에 식각 공정시 웨이퍼에 비하여 더 많은 파티클을 생성하게 되는 파티클 소스로 작용하는 문제가 발생한다. 그리고, 상술한 바와 같이 제작된 종래의 실리콘 링의 경우 커프 로스(Kerf Loss)가 1mm 이상으로 많아 생산 원가가 높은 단점이 있다.Since the polishing after grinding is single-leaf single-sided polishing using a wax process, the flatness of the surface of the silicone ring is poor, and productivity is lowered. In addition, since the surface of the silicon ring is uneven, there is a problem that it acts as a particle source that generates more particles than the wafer during the etching process. And, in the case of the conventional silicon ring manufactured as described above, there is a disadvantage that the production cost is high because the kerf loss is greater than 1 mm.
이러한 제조방법으로 실리콘 링을 제조하게 되면 C형태로 가공하기 위해 많은 기계 가공이 필요하고 내부의 제한된 공간으로 인해 그에 따른 전용 공구가 필요하며 가공 시간이 많이 소요되는 문제점이 있었다.When a silicon ring is manufactured by this manufacturing method, a lot of machining is required to process it into a C shape, and due to the limited space inside, a dedicated tool is required and processing time is required.
또한, 슬롯을 가공 시 레이저나 방전 등 고급 장비 및 고도의 기술을 요하고, 슬롯 가공 부분이 공중에 떠 있는 상태로 별도의 고정 수단이 없어 안정적인 고정이 어려워 취성이 강한 실리콘의 경우 슬롯 부분이 쉽게 부서져 가공 수율이 나쁘고 재료 손실이 크게 되는 문제점이 있었다.In addition, advanced equipment such as laser or electric discharge and advanced technology are required when processing slots.Since the slot processing part is floating in the air and there is no separate fixing means, it is difficult to secure stable fixing. There was a problem that the processing yield was bad and the material loss was large due to being broken.
또한, 종래의 포커스 링은 소정 부위에 대한 식각으로 인해 공정불량이 발생되지 않도록 전체를 주기적으로 교체해야 하며, 이에 부품 소모 증가로 제조 단가가 상승하는 문제점이 있었다.In addition, the conventional focus ring needs to be replaced periodically so that process defects do not occur due to etching of a predetermined area, and thus, there is a problem in that the manufacturing cost increases due to increased consumption of parts.
따라서, 본 발명은 상기한 문제점을 해결하기 위하여 안출한 것으로, 그 목적은 실리콘 링을 상,하 복수개로 분리하고 외부에 탭 방식의 결합링으로 탈착 가능하게 조립함으로써 제작이 편리하고 실제 소모가 많은 부품만 교체할 수 있어 부품비를 절감하며 제품 불량을 최소화하여 제품성 및 작업효율을 최대화할 수 있는 반도체 식각장치의 결합형 실리콘 링을 제공함에 있다.Therefore, the present invention has been conceived to solve the above problems, and its purpose is to separate the silicon ring into a plurality of upper and lower parts and assemble it detachably with a tap-type coupling ring on the outside, so that it is convenient to manufacture and consume a lot of actual consumption. It is to provide a bonded silicon ring of a semiconductor etching device that can maximize product quality and work efficiency by reducing parts cost and minimizing product defects because only parts can be replaced.
상기한 목적을 달성하기 위한 본 발명의 실시 예에 따른 반도체 식각장치의 결합형 실리콘 링은 상부 척과 연결 선상에 놓여지는 제1 실리콘 링과, 상기 제1 실리콘 링의 하부에 위치하되, 간격맞춤링에 의해 일정 간격 이격되도록 배치되며, 가스의 흐름을 유도하도록 다수개의 슬롯이 형성되는 제2 실리콘 링과, 상기 제1 실리콘 링과 제2 실리콘 링의 외부에 구비되어 제1 실리콘 링과 제2 실리콘 링을 연결하는 결합링과, 상기 제1 실리콘 링과 결합링에 구비되어 결합링을 제1 실리콘 링에 체결하는 제1체결부와, 상기 제2 실리콘 링과 결합링에 구비되어 결합링을 제2 실리콘 링에 체결하는 제2체결부를 포함할 수 있다.In order to achieve the above object, the combined silicon ring of the semiconductor etching apparatus according to an embodiment of the present invention includes a first silicon ring placed on a connection line with an upper chuck, and a gap fitting ring disposed below the first silicon ring. The second silicon ring is disposed to be spaced apart from each other by a predetermined interval and has a plurality of slots formed to induce the flow of gas, and the first silicon ring and the second silicon ring are provided outside the first silicon ring and the second silicon ring.
