摘要： A vertical NAND flash memory device includes a substrate having a face and a string of serially connected flash memory cells on the substrate. A first flash memory cell is adjacent the face, and a last flash memory cell is remote from the face. The flash memory cells include repeating layer patterns that are stacked on the face, and a pillar that extends through the series of repeating layer patterns. The pillar includes at least one oblique wall. At least two of the series of repeating layer patterns in the string are of different thicknesses.

摘要： NAND-type flash memory devices and methods of fabricating the same are provided. The NAND-type flash memory device includes a plurality of isolation layers running parallel with each other, which are formed at predetermined regions of a semiconductor substrate. This device also includes a string selection line pattern, a plurality of word line patterns and a ground selection line pattern which cross over the isolation layers and active regions between the isolation layers. Source regions are formed in the active regions adjacent to the ground selection line patterns and opposite the string selection line pattern. The source regions and the isolation layers between the source regions are covered with a common source line running parallel with the ground selection line pattern.
