A semiconductor substrate having an underlying conductive pattern is loaded into a process chamber(S200). Various source gases are injected into the process chamber to deposit a phase change layer(S210). After depositing the phase change layer, reactive byproducts in the process chamber are exhausted(S220). A process gas used in the forming of the phase change layer includes germanium source gas. The germanium source gas includes one selected from -N=C=O, -N=C=S, -N=C=Se, -N=C=Te, -N=C=Po, and -C N.

    Abstract: A method for forming a phase change material layer and a method for manufacturing a phase change memory device are provided to implement excellent junction characteristic with a lower layer and to implement excellent electrical characteristic by using plasma whose hydrogen gas is properly controlled. Hydrogen gas of a first flux is introduced into a reactive chamber where a substrate(10) is loaded to form a first plasma. A cyclic chemical vapor deposition process using first, second, and third precursors is performed in the chamber where the first plasma is formed to form a lower phase change material layer(20) on the substrate. The lower phase change material layer has a first dimension of grain. Hydrogen gas of a third flux smaller than the first flux is introduced into the chamber to form a second plasma. A cyclic chemical vapor deposition process using first, second, and third precursors is performed in the chamber where the second plasma is formed to form an upper phase change material layer(30) on the substrate. The upper phase change material layer has a second dimension of grain smaller than the first dimension.
