ABSTRACT:
A cold cathode structure, useful for field emission displays, is disclosed. A thin resistive silicon film is disposed on a glass substrate; conductive emitter tips are disposed on top thereof. An alloy of amorphous silicon and amorphous carbon is used for the emitter tips. The proportion of the carbon in the alloy increases, gradually or abruptly, from the base to the top of the emitter tips.
The carbon gradient is implemented during the process step, in which an n-type silicon layer is formed from which the emitter tips are made in subsequent masking and etching steps. The amount of carbon makes the emitter tips harder and gives lower work function at greater stability. Moreover, the carbon gradient allows for additional sharpening of the emitter tips.
