    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.

    摘要: A method of fabricating a phase change memory device includes the use of first, second and third polishing processes. The first polishing process forms a first contact portion using a first sacrificial layer and the second polishing process forms a phase change material pattern using a second sacrificial layer. After removing the first and second sacrificial layers to expose resultant protruding structures of the first contact portion and the phase change material pattern, a third polishing process is used to polish the resultant protruding structures using an insulation layer as a polishing stopper layer.

    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 dielectric layer is formed on a region of a microelectronic substrate. A sacrificial layer is formed on the dielectric layer, and portions of the sacrificial layer and the dielectric layer are removed to form an opening that exposes a portion of the region. A conductive layer is formed on the sacrificial layer and in the opening. Portions of the sacrificial layer and the conductive layer on the dielectric layer are removed to leave a conductive plug in the dielectric layer and in contact with the region. Removal of the sacrificial layer and portions of the conductive layer on the dielectric layer may include polishing to expose the sacrificial layer and to leave a conductive plug in the sacrificial layer and the dielectric layer, etching the sacrificial layer to expose the dielectric layer and leave a portion of the conductive plug protruding from the dielectric layer, and polishing to remove the protruding portion of the conductive plug.
