The multi-layer stacked structure includes a stair structure and a non-stair structure. A plurality of memory structures are located in the non-stair structure to form a memory array region, and each memory structure passes through the conductive layers and the insulating layers. A plurality of bow-height adjustment features are located in a second region of the semiconductor substrate.
