Web29 okt. 2024 · Inserted to pattern the most critical layers of the chips’ back-end-of-line (BEOL), it enabled printing metal lines with pitches as tight as 36-40nm. With an extremely short wavelength of 13.5nm, EUV lithography has been introduced to succeed 193nm (immersion) lithography – a transition that was dictated by the Rayleigh equation for … WebUnlike planar NAND, where cell pitch is defined by lithography, pitch in 3D NAND is determined by the film thickness. As such, precise control of layer-to-layer deposition uniformity is extremely important. Currently, commercial 3D NAND products in high-volume manufacturing have layers ranging from 32 to 48 pairs, ...
