3D NAND: Challenges beyond 96-Layer Memory Arrays

Web26 aug. 2024 · Photolithography is an integrated circuit fabrication process which plays an important role in the fabrication of different devices or different structures on devices. The photolithography process imprints the specific pattern on the wafer. It begins using a photoresist (Polymer) material, which is poured evenly onto the wafer while spins. Webo Repeat burn -focus- stigmate-apture steps at different location until a small (~ 20 nm) round spot is seen on screen. The stigmate-focus steps should be done with a magnification around 200KX at least. Make sure scanning is not rotated in SEM software. Do not change any setting of the beam including focus, stigmate, and aperture from now on.
