WebKeywords: Double Patterning, Litho-Etch-Litho- Etch, Critical Dimension, Organic Planarization Layer 1. Introduction Double patterning and multiple patterning lithography [1] have provided an extension of 193nm immersion lithography beyond 32nm-node for the semiconductor industry. Compared with single 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. pop up 5th wheel hitch

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. pop up 70th birthday cards for women
