    摘要: A structure and method for forming an column electrode for a field emission display device wherein the column electrode is disposed beneath the field emitters and the row electrode. In one embodiment, the present invention comprises depositing a resistor layer over portions of a column electrode. Next, an inter-metal dielectric layer is deposited over the column electrode. In the present embodiment, the inter-metal dielectric layer is deposited over portions of the resistor layer and over pad areas of the column electrode. After the deposition of the inter-metal dielectric layer, the column electrode is subjected to an anodization process such that exposed regions of the column electrode are anodized. In so doing, the present invention provides a column electrode structure which is resistant to column to row electrode shorts and which is protected from subsequent processing steps.
