Abstract
본 발명은 필드에미션 디바이스에서 방출되는 전류밀도를 크게 하기 위해 그 에미터 팁을 구조변경한 필드 에미션 디바이스에 관한 것이다. 이를 위한 본 발명은, 기판과, 이 기판상에서 돌출되어 전류를 방출하는 다수의 필드에미터 팁과, 상기 필드에미터 팁에서 전류가 방출되도록 그 주변에 전기장에 형성시키도록 소정의 전압이 인가되는 다수의 게이트 전극을 구비한 필드 에미션 디바이스에 있어서, 상기 필드에미터 팁이 중공형의 분화구 형상으로 된 것을 특징으로 하는데, 이로써 방출되는 전류밀도를 크게할 수 있다.The present invention relates to a field emission device in which the emitter tip is restructured to increase the current density emitted from the field emission device. To this end, the present invention provides a substrate, a plurality of field emitter tips protruding from the substrate, and a predetermined voltage is applied to form an electric field in the periphery thereof so that the current is emitted from the field emitter tips. In a field emission device having a plurality of gate electrodes, the field emitter tip has a hollow crater shape, thereby increasing the current density emitted.
