    摘要: A thin film including multi components and a method of forming the thin film are provided, wherein a method according to an embodiment of the present invention, a substrate is loaded into a reaction chamber. A unit material layer is formed on the substrate. The unit material layer is a mosaic atomic layer composed of two kinds of precursors containing components constituting the thin film. The inside of the reaction chamber is purged, and the MAL is chemically changed. The method of forming the thin film of the present invention requires fewer steps than a conventional method while retaining the advantages of the conventional method, thereby allowing a superior thin film yield in the present invention than previously obtainable.

    摘要: An amorphous high-k thin film for a semiconductor device and a manufacturing method thereof are provided. The amorphous high-k thin film includes Bi, Ti, Al, and O. Since a BTAO based amorphous dielectric thin film is used as a dielectric material of a DRAM capacitor, a dielectric constant is more than 25, and an increase of a leakage current caused in reducing a physical thickness of the dielectric thin film can be prevented. Accordingly, it is very useful for the integration of the semiconductor device.

    摘要: A capacitor for use in a semiconductor device, a method of fabricating the capacitor, and an electronic device adopting the capacitor, wherein the capacitor includes upper and lower electrodes, each formed of a platinum group metal; a thin dielectric layer disposed between the upper and lower electrodes; and a buffer layer disposed between the lower electrode and the thin dielectric layer, the buffer layer including a metal oxide of Group 3, 4, or 13. In an embodiment, the method of fabricating includes absorbing CO on a surface of a lower electrode of a platinum group metal, placing the lower electrode under a reducing atmosphere to produce a lattice oxygen, using the lattice oxygen to form a thin dielectric layer by performing an ALD process using a precursor for the thin dielectric layer, and forming an upper electrode of a platinum group metal on the thin dielectric layer.
