Description
본 발명은 마스크 세정액 조성물, 구체적으로 증착 공정에서 사용되는 마스크 상의 각종 유기물, 특히 유기 파티클의 제거가 용이한 마스크 세정액 조성물에 관한 것이다.The present invention relates to a mask cleaning liquid composition, and specifically to a mask cleaning liquid composition that facilitates the removal of various organic substances, especially organic particles, on masks used in a deposition process.
평판 디스플레이(flat panel display, FPD)는 표시장치로서 주목받고 있으며, 그 중에서도 액정표시장치와 OLED(Organic Light Emitting Diode)가 관심의 대상이 되고 있다.Flat panel displays (FPDs) are attracting attention as display devices, and among them, liquid crystal displays and OLEDs (Organic Light Emitting Diodes) are attracting attention.
현재 디스플레이로서 가장 많이 사용되고 있는 액정표시장치는, 기존의 CRT (Cathode ray tube; 음극선관)에 비해 가볍고 부피가 작으며 저전력 등의 장점을 가지고 있다. 그러나 자체발광이 아니기 때문에 후면광(Backlight)을 사용하여야 하며, 액정을 사용하여 시야각이 제한을 받는 단점이 있다.Liquid crystal displays, which are currently most widely used as displays, have advantages such as lightness, small volume, and low power compared to existing CRTs (cathode ray tubes). However, since it is not self-luminous, a backlight must be used, and the viewing angle is limited due to the use of liquid crystal.
이에 비해 OLED 소자는 저전압구동, 높은 발광 효율, 넓은 시야각, 빠른 응답속도 등의 장점이 있으며, 무엇보다도 자체발광형이기 때문에 후면광 등이 필요하지 않은 장점이 있다. 이러한 OLED 소자는 자체발광을 하는 발광 유기물을 사용하여 음극과 양극으로부터 공급된 전자와 정공이 재결합되면서 발광이 일어나게 된다.In comparison, OLED devices have advantages such as low-voltage driving, high luminous efficiency, wide viewing angle, and fast response speed, and above all, because they are self-emitting, they do not require backlighting. These OLED devices use light-emitting organic materials that self-emit, and light is emitted when electrons and holes supplied from the cathode and anode are recombined.
이런 OLED와 같은 반도체 디바이스 또는 평판 디스플레이는 제조 공정 중 각종 발광층, 정공 주입층, 정공 수송층, 전자 수송층, 전자 주입층 등과 같은 유기물층을 형성하기 위하여 마스크를 이용하여 유기물의 증착을 수행하게 된다. 이때, 마스크의 표면에도 유기물이 부착되게 되며, 이렇게 부착된 유기물로 인하여 마스크로 형성된 패턴의 형상이 변형될 수 있다. 이는, 증착공정의 효율 저하를 야기하며, 제조되는 반도체 디바이스 또는 평판 디스플레이의 성능에도 영향을 미칠 수 있으므로, 마스크에 증착된 유기물을 제거해야 할 필요가 있다.During the manufacturing process of semiconductor devices such as OLED or flat panel displays, organic materials are deposited using masks to form organic material layers such as various light-emitting layers, hole injection layers, hole transport layers, electron transport layers, and electron injection layers. At this time, organic substances are also attached to the surface of the mask, and the shape of the pattern formed by the mask may be deformed due to the organic substances attached in this way. This causes a decrease in the efficiency of the deposition process and may also affect the performance of the semiconductor device or flat panel display being manufactured, so it is necessary to remove the organic material deposited on the mask.

대한민국 등록특허 제1388283호는 마스크 세정장치에 관한 것으로서, 초음파를 발생시켜 세정액에 잠겨있는 마스크를 세정하는 초음파 세정부; 상기 초음파 세정부의 세정액 배출과 공급을 위한 세정액 순환부를 포함하고, 상기 초음파 세정부에서의 초음파는 주파수가 75KHz 이상 90KHz 이하이며, 세기가 800W 이상 1100W 이하이고, 상기 세정액은 NMP(N-Methyl Pyrrolidinone; N-메틸피롤리딘온) 혼합물인 것을 특징으로 하는 마스크 세정장치에 관한 내용을 개시하고 있다.Republic of Korea Patent No. 1388283 relates to a mask cleaning device, which includes an ultrasonic cleaning unit that generates ultrasonic waves to clean a mask submerged in a cleaning solution; It includes a cleaning liquid circulation unit for discharging and supplying the cleaning liquid of the ultrasonic cleaning unit, and the ultrasonic waves in the ultrasonic cleaning unit have a frequency of 75 KHz to 90 KHz, an intensity of 800 W to 1100 W, and the cleaning liquid is NMP (N-Methyl Pyrrolidinone). ; N-methylpyrrolidinone) mixture is disclosed.
그러나, 종래 마스크 세정액에 사용되던 N-메틸-2-피롤리돈(NMP)은 유독물질로서, 구체적으로 국립환경과학원 제2014-25호에 따르면 0.3 중량% 이상 함유시 유독물로 분류되는 물질이다. NMP가 포함된 마스크 세정액을 사용할 경우 인체에 유해할 뿐만 아니라 환경적인 측면에서도 좋지 않다.However, N-methyl-2-pyrrolidone (NMP), which has been used in conventional mask cleaning solutions, is a toxic substance and, specifically, according to National Institute of Environmental Research No. 2014-25, it is classified as a toxic substance when it contains more than 0.3% by weight. Using a mask cleaning solution containing NMP is not only harmful to the human body, but is also bad for the environment.
또한, 마스크 세정 공정은 제조 공정 상황에 따라 가동 시간이 결정 되는 관계로 대기 상태에서 장기 보관 후 성능 저하가 발생 하지 않아야 한다. 특히 대기 중에 노출 되는 관계로 수분 흡수에 대하여 성능 저하가 발생 하지 않아야 한다. In addition, since the operation time of the mask cleaning process is determined by the manufacturing process conditions, performance degradation should not occur after long-term storage in standby mode. In particular, there should be no degradation in performance due to moisture absorption due to exposure to the atmosphere.
한편, 전술한 발광층, 정공 주입층, 정공 수송층, 전자 수송층, 전자 주입층 등과 같은 유기물층을 형성할 때 그 성능을 개선하기 위하여 유기 파티클의 사용이 증가되고 있으나, 이러한 유기 파티클은 대부분 불용해성을 나타내기 때문에 세정이 용이하지 않은 문제가 발생하고 있다.Meanwhile, the use of organic particles is increasing to improve the performance of organic layers such as the above-mentioned light-emitting layer, hole injection layer, hole transport layer, electron transport layer, and electron injection layer. However, most of these organic particles are insoluble. There is a problem that it is not easy to clean because of the moisture.
그러므로, NMP와 같은 환경규제물질을 포함하지 않으면서도, 세정력이 우수, 특히 유기 파티클에 대한 세정력이 우수하고 수분 흡수에 따른 성능 저하가 발생하지 않으며, 공정 운전에 용이한 마스크 세정액의 개발이 요구되고 있다.Therefore, there is a need to develop a mask cleaning solution that does not contain environmentally regulated substances such as NMP, has excellent cleaning power, especially against organic particles, does not deteriorate performance due to moisture absorption, and is easy to process. there is.
