摘要： A phase changeable memory device is manufactured by forming at least one insulating layer on a substrate. A preliminary first electrode is formed on the insulating layer. The preliminary first electrode is partially etched to form a first electrode electrically connected to the substrate. After the preliminary first electrode is formed, both sidewalls of the preliminary first electrode are partially etched isotropically to form a first electrode having a uniform width and height. A phase changeable material layer pattern and a second electrode are subsequently formed on the first electrode. Related devices also are described.

摘要： In an embodiment, a chemical mechanical polishing method for a substrate having a first layer and a stepped portion. A surface of the first layer is positioned above an upper face of the stepped portion. A polishing process for selectively removing the stepped portion is performed on the first layer by using a first slurry composition that has a self-stopping characteristic so that the first layer is changed into a second layer having a substantially flat surface. A second polishing process is performed using a second slurry composition that does not have the self-stopping characteristic, until the upper face of the stepped portion is exposed.
