In an effort to deal with these challenges, NAND flash gadget manufacturers are aggressively pursuing several types of 3D VIM designs. Although the precise supplies required in every of those structures are totally different, all of those approaches require alternating layers of silicon-primarily based movies. Each pair of alternating layers is used to form a reminiscence cell, and as much as 64 pairs of alternating layers are anticipated for use within the formation of a VIM chip. Using this processing strategy, underlying movie roughness and defects inside every layer can potentially be magnified while build up the VIM structure. To manage these problems and guarantee high yields, distinctive nano-particle management (required to cut back defectivity) and extremely-easy film deposition (required to keep away from phrase line edge variability, and hence phrase line performance variations) are both production necessities.
