Silicidation of the top surface of Si tips with a Nb gate structure ha
s been carried out to improve the emission behavior of Si field emitte
r arrays (FEAs). A Pt layer with a thickness of 5-10 nm was deposited
through the gate opening and annealed at 850 degrees C. The electron e
mission was enhanced by a factor of 10 and the average emission per ti
p was 3.5 mu A for a 10X 10 FEA. Fowler-Nordheim plots indicated the d
ecrease in work function after silicidation. (C) 1998 American Vacuum
