WebThe second litho-etch step transfers the other half of the pattern onto the hard mask and the whole pattern is then transferred to the substrate through an etching process. A second DP technique is called self-aligned DP (SADP) [BEN 08, SHI 09] and uses a lithographic pattern itself to position a higher density pattern without the need for advance mask … Weblitho–etch–litho–etch (LELE) DP3–5) or the spacer deﬁned DP (SDDP).6) Both of these approaches require wafer processing outside of the lithography cluster for etch or thin ﬁlm deposition.
