Abstract
다수의 전자빔 통과공이 형성된 유공부를 구비한 새도우마스크와 이의 제조방법에 관한 것으로, 박판부재의 감광막을 노광시키기 위한 전자빔 통과공의 노광패턴이 형성된 마스크의 관통공 모퉁이부에 인입부가 형성되어 노광 후 식각된 전자빔 통과공이 중앙부 간격과 상하단부의 간격이 동일하게 형성된 것에 그 특징이 있으며, 이는 전자빔의 단면이 상대적으로 줄어드는 것을 방지하여 화상의 휘도차이가 발생되는 것을 방지할 수 있는 이점을 가진다.The present invention relates to a shadow mask having a hole formed with a plurality of electron beam through holes, and a method of manufacturing the same, wherein an inlet is formed at a corner of a through hole of a mask on which an exposure pattern of an electron beam through hole for exposing a photosensitive film of a thin plate member is formed. The etched electron beam through hole is characterized in that the center portion and the upper and lower intervals are formed equally, which has the advantage of preventing the luminance difference of the image from being generated by preventing the cross section of the electron beam from decreasing relatively.
