ABSTRACT:
A method is available for producing planar field emission elements such as used in camcorder view finder screens, instrument display panels, computer monitors, television displays and similar systems. Prior known methods are simplified to avoid the need for precision milling while controlling precise via hole diameters and producing wider via passage to eliminate shorting. The method involves the use of electroplating steps to reduce etched via hole diameters, using different metals to permit selective separation.
