Abstract
반도체 및 디스플레이 공정과 같이 진공의 높은 청결도의 진공이 필수적으로 요구되어 지는 산업분야가 확대됨에 따라 건식진공펌프의 중요성은 급격히 증대되어 왔다. 다단루츠형 진공펌프와 함께 건식진공펌프 양대 축의 하나를 형성하는 스크류형 건식진공펌프는 공정부산물 발생이 많은 고 난이도 응용분야에서 그 장점을 발휘하여 왔다. 최근 들어 에너지 효율이 획기적으로 개선된 스크류형 건식진공펌프의 개발이 활발히 진행되고 있다. 이 총설논문에서는 스크류형 건식진공펌프의 전반적 기술사항들을 살펴보고 실제 반도체 공정에의 응용 및 스크류형 건식진공펌프의 향후 발전 방향에 대하여 살펴보았다. As the industry requiring clean vacuum condition like semiconductor and display manufacturing expands, importance of dry vacuum pumps has been increased. Screw-type dry vacuum pump, occupying major share with multi-stage roots pump in dry-pump market, has big strength specially in harsh application area accompanying serious by-product accumulation. Recently, development in screw-type pump has been focused on improving energy efficiency. In this article, technology of screw-type dry vacuum pump is reviewed and the requirement for actual industrial application is considered. In addition, the expected evolution for screw-type dry pump in near future is also described.
