3D DRAM manufacturing
Process flow for 3D DRAM
Xiao1) provides the most detailed description of the processes used to manufacture 3D DRAM and NAND devices. Such a detailed public explanation is rare to find and applies only to two types of devices for advanced technology nodes. Nevertheless, it provides a detailed understanding of the various process loops for each mask.
