    摘要: A method of forming a phase change layer using a Ge compound and a method of manufacturing a phase change memory device using the same are provided. The method of manufacturing a phase change memory device included supplying a first precursor on a lower layer on which the phase change layer is to be formed, wherein the first precursor is a bivalent precursor including germanium (Ge) and having a cyclic structure. The first precursor may be a cyclic germylenes Ge-based compound or a macrocyclic germylenes Ge-based, having a Ge—N bond. The phase change layer may be formed using a MOCVD method, cyclic-CVD method or an ALD method. The composition of the phase change layer may be controlled by a deposition pressure in a range of 0.001 torr-10 torr, a deposition temperature in a range of 150° C. to 350° C. and/or a flow rate of a reaction gas in the range of 0-1 slm.

    摘要: A method of forming a phase change layer may include providing a bivalent first precursor having germanium (Ge), a second precursor having antimony (Sb), and a third precursor having tellurium (Te) onto a surface on which the phase change layer is to be formed. The phase change layer may be formed by CVD (e.g., MOCVD, cyclic-CVD) or ALD. The composition of the phase change layer may be varied by modifying the deposition pressure, deposition temperature, and/or supply rate of reaction gas. The deposition pressure may range from about 0.001-10 torr, the deposition temperature may range from about 150-350° C., and the supply rate of the reaction gas may range from about 0-1 slm. Additionally, the above phase change layer may be provided in a via hole and bounded by top and bottom electrodes to form a storage node.
