Abstract:
A method of manufacturing a field emission device is provided to improve the uniformity of electron emission by accurately aligning an emitter with a center portion of a gate hole. A cathode electrode(112) and a light blocking layer(120) are formed on a substrate(110), and then the light blocking layer is patterned to form a blocking layer hole(121) for exposing the cathode electrode. An insulating layer(130) and a gate material layer are formed on the light blocking layer, and then the gate material layer is patterned to form a gate electrode(140). A photoresist(170) is applied on the gate electrode to cover a gate electrode hole formed on the gate electrode, and then is exposed and developed to form a resist hole(171). The insulating layer is etched through the resist hole to form an insulating hole(131). The gate electrode is etched to form a gate hole(141), and then the photoresist is removed. An emitter is formed on the exposed cathode electrode.
