    摘要: Three-dimensional (3D) memory with control the array and control circuitry in separately processed and bonded wafers is described. In one example, a non-volatile storage component includes a first die including a three-dimensional (3D) array of non-volatile storage cells and a second die bonded with the first die. The second die includes CMOS (complementary metal oxide semiconductor) circuitry to access the 3D array of non-volatile storage cells. By processing the CMOS circuitry and array on separate wafers, the periphery CMOS and interconnects do not have to withstand the thermal cycles involved in processing the memory array, which enables optimizations for the CMOS transistors and the use low resistive material for interconnects.

    摘要: A memory device, a semiconductor device and manufacturing methods for forming the memory device and the semiconductor device are provided. The memory device include a stacking structure, a switching layer, channel layers and pairs of conductive pillars. The stacking structure includes alternately stacked isolation layers and word lines, and extends along a first direction. The stacking structure has a staircase portion and a connection portion at an edge region of the stacking structure. The connection portion extends along the staircase portion and located aside the staircase portion, and may not be shaped into a staircase structure. The switching layer covers a sidewall of the stacking structure. The channel layers cover a sidewall of the switching layer, and are laterally spaced apart from one another along the first direction. The pairs of conductive pillars stand on the substrate, and in lateral contact with the switching layer through the channel layers.
