Abstract:
A method for fabricating a base plate for a field emission device, the method comprising the steps of:forming a first conducting layer on a substrate, the first conducting layer having an emitter formed thereon;forming a first insulating layer over the first conducting layer;forming a second conductive layer over the first insulating layer;forming a second insulating layer over the second conductive layer;forming a third conductive layer over the second insulating layer;planarizing said layers such that a distal most portion of the third conductive layer, defined with respect to the first conductive layer, is spaced from the first conductive layer by a distance which is equal to or less than a distance which a distal most portion of the second conductive layer, defined with respect to the first conductive layer, is spaced from the first conductive layer; and whereinthe step of forming a second conductive layer includes the step of depositing a layer of a first conductive material; andthe step of forming a third conductive layer includes the step of depositing a layer of the first conductive material deposited in the step of forming a second conductive layer.
