본 발명은 포토마스크용 펠리클(Pellicle)에 관한 것으로서, 특히, 펠리클이 설치되는 상부프레임의 저면부분에서 레버에 의하여 분리되는 하부프레임을 오링으로 밀봉한 상태로 결합시키고, 평상시에는 상기 상부프레임과 하부플레임에 각각 형성된 다수의 핀삽입공과 하부핀삽입공에 고정핀을 삽입하여 양자를 고정하여 하부프레임의 저면에 고정된 포토마스크에 리소그라피공정을 진행한 후 포토마스크에 부착된 하부프레임을 재사용하므로 펠리클의 교체작업을 용이하게 하도록 하는 펠리클 분리형 프레임구조에 관한 것이다.The present invention relates to a pellicle (Pellicle) for the photomask, in particular, the lower frame separated by the lever in the bottom portion of the upper frame in which the pellicle is installed in an O-ring sealed state, usually the upper frame and the lower A plurality of pin insertion holes and lower pin insertion holes formed in the flame are inserted into the fixing pins to fix both, and the lithography process is performed on the photomask fixed to the bottom of the lower frame, and then the lower frame attached to the photomask is reused. It relates to a separate pellicle frame structure to facilitate the replacement of the pellicle.

일반적으로, 웨이퍼 상에 임의의 패턴을 형성하기 위한 방법으로는 포토리소그라피(Photo Lithography)공정이 이용되고 있다. 이 공정은 식각베리어로서 감광막 패턴(Photoresist Pattern)을 형성하는 공정과; 상기 포토레지스트 패턴을 이용하여 식각대상층을 식각하는 공정으로 구분되며, 상기 감광막패턴을 형성하는 공정은, 식각대상물 상에 감광막을 도포하는 공정과; 특정 마스크를 이용하여 도포된 감광막을 노광하는 공정 및 노광된 부분 혹은 노광되지 않은 부분을 임의의 용액으로 제거하는 현상공정등으로 이루어진다.In general, a photolithography process is used as a method for forming an arbitrary pattern on a wafer. This process includes forming a photoresist pattern as an etching barrier; The photoresist pattern may be divided into a process of etching an etching target layer, and the process of forming the photoresist pattern may include: applying a photoresist film on the etching target object; And a developing process of removing the exposed or unexposed portions with an arbitrary solution.

상기 리소그라피공정에는 축소 노광용 마스크를 사용하여 패턴을 형성하게 되는 것으로서, 반도체 제조용 포토마스크를 보호하기 위하여서는 장착되는 펠리클에는 미세한 먼지의 유입을 차단하는 에어필터가 벤트홀(Vent)에 장착되어져 있다.In the lithography process, a pattern is formed by using a reduction exposure mask, and in order to protect the photomask for semiconductor manufacturing, an air filter for blocking the inflow of fine dust is installed in the vent hole.

상기 펠리클은, 감광막에 부착되어 프레임에 지지되어지고, 부착되어지는 얇고 광학적으로 투과되는 니트로셀룰로스(Nitrocellulose)등과 같은 투명필림이다. 이 것은 광학적인 노광시스템의 이미지 플레인 내에 있는 이물질에 의하여 야기되는 프린팅된 결함을 줄여주고, 결함을 제거하기 위하여 사용된다.The pellicle is a transparent film such as thin, optically transmitted nitrocellulose, which is attached to the photosensitive film, supported by the frame, and attached thereto. This is used to reduce printed defects caused by foreign matter in the image plane of the optical exposure system and to eliminate the defects.

도 1은 종래의 포토마스크용 펠리클의 구조를 보인 도면이다.1 is a view showing the structure of a conventional photomask pellicle.

종래의 구성을 살펴 보면, 얇고 광학적으로 투과되는 투명필림인 펠리클(1)과; 상기 펠리클(1)을 저면에서 펠리클접착부(2)로 접착된 상태로 지지하는 프레임부재(3)와; 상기 프레임부재(3)의 저면에 포토마스크접착부(4)와 라이너(5)에 의하여 접착되고 레이저광에 의하여 패턴이 형성되는 포토마스크(6)로 구성된다.Looking at the conventional configuration, the pellicle (1) is a transparent film that is thin and optically transmitted; A frame member (3) for supporting the pellicle (1) in the state bonded to the pellicle adhesive portion (2) from the bottom; The photomask 6 is bonded to the bottom of the frame member 3 by the photomask adhesive part 4 and the liner 5, and a photomask 6 is formed by a laser beam.

상기 펠리클(1)은 상기 포토마스크(6)로 공급될 수 있는 이물질을 차단하여서 포토마스크(6)의 사용수명을 연장하고, 세정주기를 연장하며, 반복적인 사용시 오염원으로 격리하는 역활을 하게 된다.The pellicle 1 serves to prolong the service life of the photomask 6, to extend the cleaning cycle, and to isolate the contaminant during repeated use by blocking foreign substances that may be supplied to the photomask 6. .

그런데, 상기한 종래의 펠리클(10)은, 프레임부재(3)에 펠리클접착부(2)에 의하여 접착되어지고, 포토마스크(6) 역시 상기 프레임부재(30)에 포토마스크접착부(4)에 의하여 접착되어진다.By the way, the conventional pellicle 10 is bonded to the frame member 3 by the pellicle adhesive portion 2, and the photomask 6 is also attached to the frame member 30 by the photomask adhesive portion 4. To be bonded.

상기 펠리클접착부(2)와 펠리클접착부(4) 모두 양면 접착테이프 혹은 핫멜트(Hot-Melt)에 의하여 일정한 압력을 가하여 접착되어지므로 펠리클(1)의 수명이 다하거나 파손되어 교체하는 경우, 포토마스크(6) 표면의 접착제를 제거하기 매우 어려운 문제점을 지닌다.When both the pellicle adhesive portion 2 and the pellicle adhesive portion 4 are bonded by applying a constant pressure by a double-sided adhesive tape or hot-melt (Hot-Melt), the life of the pellicle (1) is damaged or replaced when the photomask ( 6) It is very difficult to remove the adhesive on the surface.

본 발명은 이러한 점을 감안하여 안출한 것으로서, 펠리클이 설치되는 상부프레임의 저면부분에서 레버에 의하여 분리되는 하부프레임을 오링으로 밀봉한 상태로 결합시키고, 평상시에는 상기 상부프레임과 하부플레임에 각각 형성된 다수의 핀삽입공과 하부핀삽입공에 고정핀을 삽입하여 양자를 고정하여 하부프레임의 저면에 고정된 포토마스크에 리소그라피공정을 진행한 후 포토마스크에 부착된 하부프레임을 재사용하므로 펠리클의 교체작업을 용이하게 하도록 하는 것이 목적이다.The present invention has been made in view of this point, the lower frame is separated by the lever in the bottom portion of the upper frame in which the pellicle is coupled in an O-ring sealed state, usually formed in the upper frame and the lower frame, respectively Insert the fixing pins into the plurality of pin insertion holes and the lower pin insertion holes to fix them, and then proceed with the lithography process on the photomask fixed to the bottom of the lower frame, and then reuse the lower frame attached to the photomask. The purpose is to make it easy.
