The LLE-DP method using a silylation freeze reaction comprises providing a substrate with a first photoresist layer thereon. A first exposure process is performed defining a first latent image in a first photoresist.

Web23 mrt. 2024 · Lithography processing. Lithography processing is a series of processing steps used to pattern masks and samples with photoresist prior to other processing steps (e.g. deposition, etching, doping). There are a variety of lithography processes that are available in the LNF. This page specifically talks about optical (UV) lithography. 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. One of important concerns of double patterning is the increasing production cost from the extra process steps and related throughput loss.
