Resist blur and line edge roughness
WebA negative resist composition is provided comprising a base polymer and an acid generator in the form of a sulfonium salt consisting of a sulfonate anion having a maleimide group and a cation having a polymerizable double bond. The resist composition adapted for organic solvent development exhibits a high resolution and improved LWR or CDU. WebNov 11, 2010 · Mask contributors to line-edge roughness (LER) have recently been shown to be an issue of concern for extreme ultraviolet lithography both in terms of the accuracy of current resist evaluation tests and in terms of the ultimate LER requirements for the 22 nm production node and beyond. More recently, it has been shown that the power spectral …
