    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: Methods of manufacturing a semiconductor device include forming integrated structures of polysilicon patterns and hard mask patterns on a substrate divided into at least an NMOS forming region and a PMOS forming region. A first preliminary insulating interlayer is formed on the integrated structures. A first polishing of the first preliminary insulating interlayer is performed until at least one upper surface of the hard mask patterns is exposed, to form a second preliminary insulating interlayer. The second preliminary insulating interlayer is etched until the upper surfaces of the hard mask patterns are exposed, to form a third preliminary insulating interlayer. A second polishing of the hard mask patterns and the third preliminary insulating interlayer is performed until the polysilicon patterns are exposed to form an insulating interlayer. The polysilicon patterns are removed to form an opening. A metal material is deposed to form a gate electrode pattern in the opening.

    摘要: Disclosed is a method of fabricating a semiconductor device including a multi-gate transistor. The method of fabricating a semiconductor device includes providing a semiconductor device having a number of active patterns which extend in a first direction, are separated by an isolation layer, and covered with a first insulating layer; forming a first groove by etching the isolation layer located between the active patterns adjacent to each other in the first direction; burying the first groove with a passivation layer; forming a second groove exposing at least a portion of both sides of the active patterns by etching the isolation layer located between the active patterns in a second direction intersecting the first direction; removing the passivation layer in the first groove; and forming a gate line filling at least a portion of the second groove and extending in the second direction.
