    摘要: A non-volatile memory device having memory elements with a channel length of, e.g., 45-55 nm or less, is fabricated using existing lithographic techniques. In one approach, patterns of first and second photomasks are transferred to the same photoresist layer. The first photomask can have openings with a given feature size F that are spaced apart by the feature size F, for instance. The second photomask has an opening which is sized to create a desired inter-select gate gap, such as 3 F or 5 F. A third photomask is used to provide protective portions in a second photoresist layer over the select gate structures. The final structure has memory elements of width F spaced apart by a distance F, and select gates of width 3 F spaced apart by 3 F or 5 F. In another approach, the patterns of three photomasks are transferred to respective photoresist layers to create an analogous final structure.
