Patent abstract
Disclosed herein are 3D NAND memory devices having an oxide semiconductor vertical NAND channel and methods for forming the same. The oxide semiconductor may have a crystalline structure. The channel of the vertically-oriented NAND string may be cylindrically shaped. The crystalline structure has an axis that may be aligned crystalline with respect to the cylindrical shape of the vertically-oriented channel substantially throughout the vertically-oriented channel. The crystalline structure may 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.
