    摘要: Example embodiments may provide phase-change material layers and a method of forming a phase-change material layer and devices using the same by generating a plasma including helium and/or argon in a reaction chamber, forming a first material layer on the object by introducing a first source gas including a first material, forming a first composite material layer on the object by introducing a second source gas including a second material into the reaction chamber, forming a third material layer on the first composite material layer by introducing a third source gas including a third material, and forming a second composite material layer on the first composite material layer by introducing a fourth source gas including a fourth material. Example embodiment phase-change material layers including carbon may be more easily and/or quickly formed at lower temperatures under the helium/argon plasma environment by providing the source gases for various feeding times. Example embodiments may also include memory devices using phase-change memory layers.

    摘要: A phase-changeable layer and a method of forming the same are disclosed. In the method, a first hydrogen gas is introduced into a reaction chamber into which a substrate is loaded at a first flow rate to form first plasma. A primary cyclic CVD process is carried out using precursors in the reaction chamber to form a lower phase-changeable layer having a first grain size on the substrate. A second hydrogen gas is introduced into the reaction chamber at a second flow rate less than the first flow rate to form second plasma. A secondary cyclic CVD process is carried out using the precursors in the reaction chamber to form an upper phase-changeable layer having a second grain size smaller than the first grain size on the substrate, thereby forming a phase-changeable layer. Thus, the phase-changeable layer may have strong adhesion strength with respect to a lower layer and good electrical characteristics.
