    摘要: The present invention relates to polyarylene sulfide, in which a ratio of a peak area of a polymer chain of a second polyarylene sulfide having a lower molecular weight than the maximum peak molecular weight to a peak area of a polymer chain of a first polyarylene sulfide having a higher molecular weight than the maximum peak molecular weight is 1.3 or less in the molecular weight distribution of the polyarylene sulfide, as measured by gel permeation chromatography using polystyrene as a standard, and a preparation method thereof. This polyarylene sulfide exhibits excellent processability and generates no burrs (flashes) or the like, and can satisfactorily mold a product requiring high molding precision.

    摘要: A phase change memory device includes a mold layer disposed on a substrate, a heating electrode, a filling insulation pattern and a phase change material pattern. The heating electrode is disposed in an opening exposing the substrate through the mold layer. The heating electrode is formed in a substantially cylindrical shape, having its sidewalls conformally disposed on the lower inner walls of the opening. The filling insulation pattern fills an empty region surrounded by the sidewalls of the heating electrode. The phase change material pattern is disposed on the mold layer and downwardly extended to fill the empty part of the opening. The phase change material pattern contacts the top surfaces of the sidewalls of the heating electrode.
