Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: forming a preliminary insulation structure having an opening that partially exposes a substrate, the preliminary insulation structure including at least two patterns of materials that have etching selectivities with respect to one another; forming an amorphous material structure on the substrate that fills the opening, wherein forming the amorphous material structure comprises: forming a preliminary amorphous material structure on the substrate and the preliminary insulation structure to fill the opening; performing a planarizing process on the preliminary amorphous material structure until the preliminary insulation structure is exposed to form the amorphous material structure confined in the opening; transforming the amorphous material structure into a single crystalline material structure by irradiating a laser beam onto the amorphous material structure; and exposing an upper portion of the single crystalline material structure by removing an uppermost pattern of the preliminary insulation structure to provide an insulation structure, the upper portion of the single crystalline material structure being a channel structure having a substantially vertical sidewall.
