    摘要: In a method of recycling a substrate having an edge portion on which a stepped portion is formed, the substrate is chemically mechanically polished using a first slurry composition including fumed silica to remove the stepped portion. The substrate is then chemically mechanically polished using a second slurry composition including colloidal silica to improve the surface roughness of the substrate. The substrate having the edge region on which the stepped portion is formed may include a donor substrate used for manufacturing a silicon-on-insulator (SOI) substrate.

    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: In methods of forming a thin ferroelectric layer and methods of manufacturing a semiconductor device, a preliminary ferroelectric layer is formed on a substrate by depositing a metal oxide including lead, zirconium and titanium. The surface of the preliminary ferroelectric layer is polished using a slurry composition including an acrylic acid polymer, abrasive particles, and water to form a thin ferroelectric layer on the substrate. The slurry composition may reduce a polishing rate of the preliminary ferroelectric layer such that removal of a bulk portion of the preliminary ferroelectric layer may be suppressed and the surface roughness of the preliminary ferroelectric layer may be improved.
