THREE DIMENSIONAL NAND DEVICE AND METHOD OF CHARGE TRAP LAYER SEPARATION AND FLOATING GATE FORMATION IN THE NAND DEVICE |
摘要 |
A monolithic three dimensional NAND string includes a vertical semiconductor channel and a plurality of control gate electrodes in different device levels. The string also includes a blocking dielectric layer, a charge storage region and a tunnel dielectric. A first control gate electrode is separated from a second control gate electrode by an air gap located between the major surfaces of the first and second control gate electrodes and/or the charge storage region includes silicide nanoparticles embedded in a charge storage dielectric. |
