    摘要: In a method of manufacturing a semiconductor device, a plurality of sacrificial layers and a plurality of insulating interlayers are repeatedly and alternately on a substrate. The insulating interlayers include a different material from a material of the sacrificial layers. At least one opening through the insulating interlayers and the sacrificial layers are formed. The at least one opening exposes the substrate. The seed layer is formed on an inner wall of the at least one opening using a first silicon source gas. A polysilicon channel is formed in the at least one opening by growing the seed layer. The sacrificial layers are removed to form a plurality of grooves between the insulating interlayers. A plurality of gate structures is formed in the grooves, respectively.
