摘要:
A method of fabricating a vertical NAND semiconductor device can include changing a phase of a first preliminary semiconductor layer in an opening from solid to liquid to form a first single crystalline semiconductor layer in the opening and then forming a second preliminary semiconductor layer on the first single crystalline semiconductor layer. The phase of the second preliminary semiconductor layer is changed from solid to liquid to form a second single crystalline semiconductor layer that combines with the first single crystalline semiconductor layers to form a single crystalline semiconductor layer in the opening.

Provided are methods of forming a phase change memory device. A semiconductor device having a lower electrode and an interlayer insulating layer may be prepared. The lower electrode may be surrounded by the interlayer insulating layer. Source gases, a reaction gas and a purge gas may be injected into a process chamber of a semiconductor fabrication device to form a phase change material layer on a semiconductor substrate. The source gases may be simultaneously injected into the process chamber. The phase change material layer may be in contact with the lower electrode through the interlayer insulating layer. The phase change material layer may be etched to form a phase change memory cell in the interlayer insulating layer. An upper electrode may be formed on the phase change memory cell.
