  • Publication number: 20240352583
    Abstract: The present invention relates to an oxide film reaction surface control agent, a method of forming an oxide film using the oxide film reaction surface control agent, a semiconductor substrate including the oxide film, and a semiconductor device including the semiconductor substrate. According to the present invention, by providing a compound having a predetermined structure as an oxide film reaction surface control agent, a deposition layer having a uniform thickness due to a difference in the adsorption distribution of the oxide film reaction surface control agent is formed as a shielding area on a substrate, thereby reducing thin film deposition rate and appropriately reducing thin film growth rate. Accordingly, even when a thin film is formed on a substrate having a complex structure, step coverage and the thickness uniformity of the thin film may be greatly improved, and impurities may be reduced.
