    摘要: Provided are methods of forming a semiconductor device. The methods include providing a first precursor and a substitute gas into a reaction chamber having a substrate therein, the first precursor having a first substituent and further providing a second precursor into the reaction chamber. Either the first precursor or the second precursor includes a metal element and the other includes a silicon element, at least one of the first substituents of the first precursor are substituted with the substitute gas, the first precursor substituted with the substitute gas is adsorbed onto the substrate, and the second precursor is reacted with the adsorbed first precursor.

    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.
