Definitions
- the present invention relates to a novel metal triamine compound, a method for preparing the same, and a composition for depositing a metal-containing thin film including the same, and more particularly, a novel metal triamine compound that can be usefully used as a precursor of a metal-containing thin film, and a It relates to a manufacturing method and a metal-containing thin film deposition composition comprising the same and a method for producing a metal-containing thin film using the metal-containing thin film deposition composition of the invention.
- high dielectric materials having excellent insulation, high dielectric constant and low dielectric loss
- high-k metal oxide materials have been proposed as alternative dielectric materials for gate or capacitor dielectrics.
