NettetThe fundamental limits of optical lithography have driven semiconductor processing research to push the envelope. Double patterning (DP) techniques including litho-etch litho-etch (LELE), litho-litho etch (LLE), and self-aligned double patterning (SADP) have become standard vernacular for near term semiconductor processing as EUV is not yet … NettetAbstract: Self-aligned spacer double patterning (SADP) scheme has been proposed as an alternative to litho-etch-litho-etch (LELE) scheme because if its superior control of the …
