  • Publication number: 20080057224
    Abstract: A method of manufacturing a thin film includes providing a metal organic precursor onto a substrate where the metal organic precursor is heated to a temperature of about 60° C. to about 95° C. and has a saturated vapor pressure of about 1 Torr to about 5 Torr. An oxidizing agent including oxygen for oxidizing the metal organic precursor is provided onto the substrate. The metal organic precursor and the oxidizing agent are chemically reacted to form the thin film including metal oxide. The thin film is easily available in a gate insulation layer of a gate structure, a dielectric layer of a capacitor, and similar circuit components.

  • Publication number: 20070292628
    Abstract: In a method of forming a metal oxide, an organic metal compound represented by the following chemical formula is introduced into a chamber to chemisorb the organic metal compound onto a substrate, M[L1]x[L2]y where M represents a metal, L1 and L2 respectively represents a first and second ligands. In addition, x and y are independently integers and a value of (x+y) is 3 to 5. An oxygen-containing compound is introduced into the chamber to form the metal oxide. The metal oxide is formed by reacting an oxygen of the oxygen-containing compound with the metal, and separating the ligand from the metal. Thus, the metal oxide having a superior step coverage and a high dielectric constant may be formed using the organic metal compound by an atomic layer deposition process.
