Abstract: 본 발명은 차세대 플렉시블디스플레이 등으로 응용이 가능한 유기박막트랜지스터 (OTFT)의 소자 안정성을 위한 유기보호박막 형성방법에 관한 것이다. 즉 용액공정을 통한 보호막 형성기술에서 사용되는 유기물의 박막특성을 향상시키는 새로운 방법으로서 봉지 특성 및 보호막 박막 이후 공정을 위한 박막 균일도를 향상시키는 효과가 있다. 유기보호막으로 사용되는 유기물을 유기보호막 하부층에 손상을 주지 않는 용매에 녹여 보호막을 형성하게 되는데 이때 유기보호막 용액에 코팅성 향상을 위한 적절한 계면활성제를 도입함으로 인해 코팅성 및 박막 균일도를 향상시킬 수 있다. 이러한 기술은 기존에 보고가 되지 않은 신규기술이다.
본 발명은 유기막박트랜지스터 (OTFT)의 어레이 (array) 소자응용을 위한 공정에서 필수적으로 적용이 되어야 되는 기술이며 유기보호막 코팅성 향상에 의한 보호막 박막 균일도를 향상시킴으로서 이후 공정에서 표면 평탄도에 기인한 공정 불량을 감소시킬 수 있는 기술이다.
