  • Publication number: 20220246708
    Abstract: A method of manufacturing a metal oxide film includes injecting a reaction gas and metal precursors into a chamber, forming a first metal precursor film on a substrate in a plasma OFF state, forming a first sub-metal oxide film by oxidizing the first metal precursor film in a plasma ON state, and forming a second metal precursor film on the first sub-metal oxide film in the plasma OFF state, where the metal oxide film has an amorphous phase, a thickness of about 20 nanometer (nm) to about 130 nm, and a dielectric constant of about 10 to about 50.

  • Patent number: 11268192
    Abstract: A thin film processing apparatus includes a susceptor and a showerhead facing the susceptor. The showerhead includes a first plate including an inner tunnel, a first injection hole, and a second injection hole. The inner tunnel extends across the first plate in a thickness direction of the first plate. The first injection hole penetrates a first surface and a second surface of the first plate on opposite sides of the first plate in the thickness direction. The second injection hole penetrates the second surface of the first plate. The second injection is connected with the inner tunnel.

  • Patent number: 11004677
    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.

  • Patent number: 10679858
    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.
