WebRenwick suggests that introducing multiple-patterning with EUV may be needed but would increase costs. “193i lithography will continue to be used with quadruple-patterning and in combination with other techniques – there is no single solution.” Figure 1. Normalized cost/layer vs. lithography method. Assist features are often used to help balance asymmetry from non-telecentricity at different slit positions, due to different illumination angles, starting at the 7 nm node, where the pitch is ~ 41 nm for a wavelength ~13.5 nm and NA=0.33, corresponding to k1 ~ 0.5. However, the asymmetry is reduced but not eliminated, since the assist features mainly enhance the highest spatial frequencies, whereas intermediate spatial frequencies, which also affect feature focus and posit…
