    Abstract: A method for manufacturing a semiconductor device having a self-aligned cell diode and a method for manufacturing a phase-change memory device using the same are provided to restrain increase of electrical resistance due to a mis-alignment of the word lines and cell diodes by using self-cell diodes being self-aligned with word lines. A conductive layer is formed on a semiconductor substrate(40). A dielectric(44) is formed on the conductive layer. The dielectric and the conductive layer are patterned in turn to form isolation trenches for exposing the substrate and word lines(WL) defined by the isolation trenches. An isolation layer(54) is formed to gap-fill the isolation trenches. Cell contact holes pass through to expose the word lines. The cell contact holes are defined by the adjacent isolation layer to be self-aligned with the word lines. Cell diodes gap-fill the cell contact holes. When the isolation trenches and the word lines are formed, a first hard mask layer is formed on the dielectric, the first hard mask layer is patterned to form a line-shaped first preliminary hard mask patterns(46'), and the dielectric is etched by using the first preliminary hard mask patterns as etch masks.
