The multiple demands of 3D NAND to enable yield and performance increase in difficulty at each generation. First generation devices, at 24-32 layer pairs, pushed process tools to extremes, going ...

Soft lithography is a fabrication technique used to create micro- and nanoscale patterns. Developed in the early 1990s by George M. Whitesides and colleagues, it simplifies pattern formation by using ...

Soft lithography facilitates the fabrication of intricate three-dimensional patterns and structures at both microscale and nanoscale dimensions. Diverging from photolithography, a technique commonly ...

(Nanowerk News) Nanotechnology and nanoscience are enabled by nanofabrication. Electron-beam lithography (EBL), which makes patterns down to a few nanometers, is one of the fundamental pillars of ...

As 40-nanometer NAND flash products are prepared for mass production, and as technologies emerge to achieve densities beyond 2 bits per cell (multilevel-cell technology), with 3- and 4-bit/cell ...

SanDisk and Toshiba announced today that they are manufacturing 256Gbit (32GB), 3-bit-per-cell (X3) 48-layer 3D NAND flash chips that offer twice the capacity of the next densest memory. The two NAND ...
