The late 1990s saw the widespread introduction of solid-state storage based around NAND Flash. Ranging from memory ... more layers on top of each other (3D NAND) and increasing the number of ...

“The change from 2D to 3D integration introduces new metrology challenges, including very high-aspect ratio structures, wafer stress driven bow and vertical gate dimension control.” The big challenge ...

It focuses on 3D NAND flash memory, a critical component in storage devices like SSDs, smartphones, and data centers, and ...

YMTC is known for its design and fabrication of 3D NAND, a flash memory in which transistor dies are stacked vertically to increase storage density. Patent applications made public in late March ...

“Unlike the traditional 2D Floating Body Cell that uses body effect to change ... NEO Semiconductor is a high-tech company focused on advancing 3D NAND flash and DRAM technologies. The company was ...

In any case, the 294 layers (including active and dummy layers) are an important milestone for YMTC and the whole flash memory industry. 232 active layers is not a record layer count for 3D NAND ...

Traditional flash memory has a single layer of cells, known as "2D planar NAND." As manufacturers shrank the cells and cell walls to increase storage density, fewer electrons resided in each cell ...
