A method for fabricating a field emission display ( ) includes the steps of providing a cathode plate ( ), providing an anode plate ( ), providing a spacer substrate ( ) made from a bulk spacer material ( ), cutting the spacer substrate ( ) to define a spacer ( ) having a surface ( ), passivating the surface ( ) of the spacer ( ) using the bulk spacer material ( ) to form a passivation layer, and disposing the spacer ( ) between the cathode plate ( ) and the anode plate ( ). A field emission display ( ) which includes a cathode plate ( ) having a plurality of electron emitters ( ), an anode plate ( ) opposing the cathode plate ( ), and a spacer ( ) extending between the cathode plate ( ) and anode plate ( ). The spacer ( ) has a passivation layer made from bulk spacer material ( ).

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).
