    摘要: A method of fabricating a semiconductor device including a channel layer includes forming a single crystalline semiconductor layer on a semiconductor substrate. The single crystalline semiconductor layer includes a protrusion extending from a surface thereof. A first polishing process is performed on the single crystalline semiconductor layer to remove a portion of the protrusion such that the single crystalline semiconductor layer includes a remaining portion of the protrusion. A second polishing process different from the first polishing process is performed to remove the remaining portion of the protrusion and define a substantially planar single crystalline semiconductor layer having a substantially uniform thickness. A sacrificial layer may be formed on the single crystalline semiconductor layer and used as a polish stop for the first polishing process to define a sacrificial layer pattern, which may be removed prior to the second polishing process. Related methods of fabricating stacked semiconductor memory devices are also discussed.

    摘要: A method of forming a semiconductor device includes: forming a pattern having trenches on a semiconductor substrate; forming a semiconductor layer on the semiconductor device that fills the trenches; planarizing the semiconductor layer using a first planarization process without exposing the pattern; performing an epitaxy growth process on the first planarized semiconductor layer to form a crystalline semiconductor layer; and planarizing the crystalline semiconductor layer until the pattern is exposed to form a crystalline semiconductor pattern.

    摘要: A method of manufacturing a stack-type semiconductor device, in which a first substrate and a second substrate are prepared so that the first substrate has a surface layer and the second substrate has an insulation layer. The first substrate and the second substrate are attached to each other to allow the surface layer to make contact with the insulation layer. The first substrate is partially separated from the second substrate to allow the surface layer to remain on a central portion of the second substrate. A sacrificial layer pattern is then formed on an edge portion of the second substrate having the surface layer. The sacrificial layer pattern and the surface layer are planarized. Thus, the sacrificial layer pattern may reduce damage to the edge portion of the second substrate so that the second substrate may have an improved flatness.
