3-D NAND control gate enhancement

Last updated:

Abstract:

Methods of forming 3D NAND devices are discussed. Some embodiments form 3D NAND devices with a control gate and a floating gate disposed between a first insulating layer and a second insulating layer. A conformal blocking liner surrounds the floating gate and electrically isolates the control gate from the floating gate. Some embodiments form 3D NAND devices with decreased vertical and/or later pitch between cells.
