摘要:
A semiconductor device for use in field emission displays includes a substrate formed from a semiconductor material, glass, soda lime, or plastic. A first layer of a conductive material is formed on the substrate. A second layer of microcrystalline silicon is formed on the first layer. This layer has characteristics that do not fluctuate in response to conditions that vary during the operation of the field emission display, particularly the varying light intensity from the emitted electrons or from the ambient. One or more cold-cathode emitters are formed on the second layer.
