Abstract:
A three-dimensional NAND memory string includes an alternating stack of insulating layers and word line layers extending in a word line direction, a memory array region in the alternating stack containing memory stack structures, a group of more than two column stairs located in the alternating stack and extending in the word line direction from one side of the memory array region, and bit lines electrically contacting the vertical semiconductor channels and extending in a bit line direction which is perpendicular to the word line direction. Each column stair of the group of N column stairs has a respective step in a first vertical plane which extends in the bit line direction, and the respective steps in the first vertical plane decrease and then increase from one end column stair to another end column stair.

Claim (Index 5):
The three-dimensional memory device of  claim 1 , wherein:\n each vertical cross-sectional view that is perpendicular to the first horizontal direction and cuts through each column stair within a group of N column stairs includes both a respective stepwise decreasing profile and a respective stepwise increasing profile between the respective first trench and the respective second trench; and each of the vertical cross-sectional profiles has (N\u22121) inter-column vertical steps between neighboring column stairs for each alternating stack.
