Abstract
본 발명은 전계 방출 소자 및 그 제조 방법에 관한 것으로서, 더욱 상세하게는, 하나의 기판에 애노드와 캐소드를 모두 형성하는 전계 방출 소자 및 그 제조 방법에 관한 것이다. 기판 위에 애노드를 형성하고 기판 위에 절연막을 형성하고 절연막 위에 애노드를 향하는 뽀족한 팁을 가지는 캐소드를 형성하고 절연막 중앙부를 식각하여 기판 및 애노드 표면 일부가 노출되고 캐소드의 팁이 돌출도록 하고 애노드를 덮는 형광체를 형성한다. 따라서, 본 발명에 따른 전계 방출 소자는 캐소드와 형광체를 하나의 기판에 수평하게 형성하여 대향하는 투명 기판을 정확히 정렬해야 번거러움을 없애므로 공정 수율을 높일 수 있고 생산성을 향상키는 효과가 있다.The present invention relates to a field emission device and a method for manufacturing the same, and more particularly, to a field emission device for forming both the anode and the cathode on one substrate and a method for manufacturing the same. A phosphor is formed on the substrate, an insulating film is formed on the substrate, and a cathode having a sharp tip facing the anode is formed on the insulating film, and the center portion of the insulating film is etched to expose a portion of the substrate and the anode surface, to expose the tip of the cathode, and to cover the anode. To form. Therefore, the field emission device according to the present invention forms a cathode and a phosphor horizontally on one substrate so that the opposite transparent substrates must be accurately aligned to eliminate the hassle, thereby increasing the process yield and improving productivity.
