Abstract
A micropoint assembly of a field emission device ("FED") including a baseplate, one or more conductors formed over the baseplate, and one or more micropoints formed over the conductor(s) is disclosed. The micropoint assembly further includes resistive structures associated with specific FED elements that limit current to a maximum level and minimize impact to remaining elements of the device. Any variation in resistivity is uniformly distributed since the same process is consistently applied across a plurality of element locations.
