Abstract :
In this study, various metal silicides including Ti and Co were applied to gated poly-Si field emitter arrays, and their emission properties have been compared. Silicides were produced by deposition of 25-nm-thick metals on emitter tips through the gate opening and subsequent rapid thermal annealing under N/sub 2/ environment with flow rate of 7.5 slpm. XRD measurement was done to look the constituent and dominant binds of metal-Si compounds. It was found that all the metal layers were completely transformed into MSi/sub 2/ (M: metal element).
