  • METHODS OF FORMING A LAYER, METHODS OF FORMING A GATE STRUCTURE AND METHODS OF FORMING A CAPACITOR
    Publication number: 20110045183
    Abstract: In a method of forming a layer, a precursor including a metal and a ligand chelating to the metal is stabilized by contacting the precursor with an electron donating compound to provide a stabilized precursor onto a substrate. A reactant is introduced onto the substrate to bind to the metal in the stabilized precursor. The precursor stabilized by the electron donating compound has an improved thermal stability and thus the precursor is not dissociated at a high temperature atmosphere, and the layer having a uniform thickness is formed on the substrate.
