Paper Abstract
We investigated the relationship between line edge roughness (LER) and the chemical gradient using the fourth Selete
Standard Resist (SSR4). Two-dimensional (half-pitch and exposure dose) matrices of resist line width and LER were
analyzed on the basis of the sensitization mechanisms of chemically amplified resists for extreme ultraviolet (EUV)
lithography. The latent images of resist patterns were successfully reproduced by assuming that LER is inversely proportional to the chemical gradient. The product of LER and normalized chemical gradient was approximately 0.2 for SSR4.
