Claims (1)
- 투명재질로 된 기판상에 불투명한 물질을 코팅하는 공정 ; 상기 불투명한 물질상에 포토레지스트를 도포하고 매스터 마스크를 사용하여 상기 포토레지스트를 노광하고 현상하여 포토레지스트패턴을 형성하는 공정 ; 상기 포토 레지스트를 식각마스크로 사용하여 상기 불투명한 물질을 에칭하여 불투명한 물질로 된 광차단막 패턴을 형성하는 공정 ; 상기 에칭공정후 포토레지스트패턴을 제거하고 새로운 포토레지스트를 상기 광차단막의 두께보다 두껍게 그리고 평탄하게 결과물의 전표면에 도포하는 공정 ; 상기 도포공정후 상기 기판의 배면에서 빛을 조사하여 상기 새로운 포토레지스트막을 노광시키는 공정 ; 및 상기 노광후, 결과물을 과도 현상처리하여 상기 광차단막 사이의 공간부에 형성된 볼곡렌즈형 투명막을 형성하는 공정을 구비한 것을 특징으로 하는 렌즈형 마스크의 제조방법.
