Fabrication of 3D NAND devices involves a challenging and complex deposition and etch process. Two etch processes have been identified as substantially impacting 3D NAND product yields: silicon ...

The part 1 of this two-article series outlined the NAND flash technology and how it transitioned from 2D to 3D NAND flash. The article also explained the current challenges in the way of density ...

For several decades, NAND Flash has been the primary technology for low-cost and large-density data storage applications. This non-volatile memory is present in all major electronic end-use markets, ...

Unlike scaling practices in 2D NAND technology, the direct way to reduce bit costs and increase chip density in 3D NAND is by adding layers. In 2013, Samsung shipped the first V-NAND product using 24 ...
