    Abstract: A method and a device for forming a highly dielectric metal oxide layer. The method includes repeatedly causing a plasma-off period and a plasma-on period while an organic metal compound and an oxidizing agent are continuously injected into a chamber. One cycle includes one plasma-off period and one plasma-on period. During the plasma-off period, a physical and chemical adsorption layer including an organic metal compound and a plurality of atomic layers is formed on a substrate. During the plasma-on period, a metal oxide layer that is thicker than two atomic layers is formed by a chemical reaction of metal atoms in the physical and chemical adsorption layer and oxygen atoms in the oxidizing agent.

    Abstract: A deposition apparatus includes a chamber, a susceptor that supports a substrate in the chamber, an upper electrode facing the susceptor, a showerhead defining a gas inlet space between the upper electrode and the susceptor, a metal source storage to store a metal source supplied to the chamber, a vaporizer to vaporize the metal source, a first gas source to supply a first gas to move the metal source toward the vaporizer, a second gas source to supply a second gas to move the metal source in the vaporizer toward the chamber, a third gas source connected to the chamber to supply a third gas into a reaction space defined between the susceptor and the upper electrode such that the third gas reacts with the metal source, and a fourth gas source connected to the chamber to supply a fourth gas used to clean an inside of the chamber.
