Abstract
A method for fabricating a diamond-like carbon field emission device (300, 800) includes the steps of: (i) forming on a column conductor (330, 830) a ballast layer (364), (ii) forming on the ballast layer (364), in registration with a central well region (332, 832) of the column conductor (330, 830), a surface emitter (370, 870) made from diamond-like carbon, (iii) forming on the ballast layer (364) and surface emitter (370, 870) a field shaping layer (374), (iv) pattering the ballast layer (364) and the field shaping layer (374) to form a ballast (365) and field shaper layer (377) having opposed edges which, with the opposed edges of the column conductor (330, 830), define smooth, continuous surfaces (371, 871), (v) depositing a blanket dielectric layer (341), and (vi) forming an emission well (360, 860) above the central well region (332, 832) of the column conductor (330, 830).
