    摘要: Disclosed herein are 3D NAND memory devices having an oxide semiconductor vertical NAND channel and methods for forming the same. The NAND string comprises a vertically-oriented cylindrically shaped channel (699), the vertically-oriented cylindrically shaped channel comprising an oxide semiconductor having a crystalline structure, the crystalline structure having an axis (a, b, or c) that is aligned crystalline with respect to the cylindrical shape of the vertically-oriented channel substantially throughout the vertically- oriented channel. The crystalline structure may, for example, have a first axis that is aligned parallel to the vertical channel, a second axis that is aligned perpendicular to a surface of the cylindrically shaped channel, etc.
