摘要:
The present invention provides metal precursors for low temperature deposition. The metal precursors include a metal ring compound including at least one metal as one of a plurality of elements forming a ring. Methods of forming a metal thin layer and manufacturing a phase change memory device including use of the metal precursors is also provided.
摘要:
In one embodiment, a phase change memory device includes an insulation structure over a substrate. The insulation structure ahs an opening defined therethrough. A first layer pattern is formed on sidewalls and a bottom of the opening. A second layer pattern is formed on the first layer pattern and substantially fills the opening.
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.
