METHOD FOR MAKING FIELD EMISSION DEVICES HAVING CORRUGATED SUPPORT PILLARS FOR BREAKDOWN RESISTANCE

摘要

A field emission device is made by providing the device electrodes, forming a plurality of corrugated insulating rods, adhering the rods to an electrode, cutting away the tops of the rods to define corrugated pillars, and finishing the device. The corrugated rods can be formed in one of three different methods. The result is low cost production of a field emission device having superior resistance to breakdown in high voltage operation.
