  • Publication number: 20250019827
    Abstract: The present invention relates to a film quality improver, a method of forming a thin film using the film quality improver, a semiconductor substrate fabricated using the method, and a semiconductor device including the semiconductor substrate. The present invention provides a compound having a predetermined structure as a film quality improver. According to the present invention, by forming a shielding area for a molybdenum-based thin film on a substrate, the deposition rate of a molybdenum-based thin film may be reduced, and the growth rate of a thin film may be controlled. Thus, even when forming a thin film using a solid compound on the substrate with a complicated structure at room temperature, step coverage and the thickness uniformity of the thin film may be greatly improved, and corrosion or deterioration may be prevented, thereby improving the crystallinity and electrical properties of a thin film.

  • Publication number: 20250003067
    Abstract: The present invention relates to a film quality improver, a method of forming a thin film using the film quality improver, and a semiconductor substrate fabricated using the method. According to the present invention, side reactions may be suppressed by using a film quality improver having a predetermined structure in a thin film deposition process, and process by-products in a thin film may be removed by appropriately controlling a thin film growth rate. As a result, even when the thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity of the thin film may be greatly improved. In addition, corrosion or deterioration may be prevented, and the electrical properties of the thin film may be improved due to improvement in the crystallinity of the thin film.

  • 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.

  • Publication number: 20240145301
    Abstract: Disclosed are a metal thin film precursor composition, a method of forming a thin film using the metal thin film precursor composition, and a semiconductor substrate fabricated using the method. The metal thin film precursor composition includes a metal thin film precursor compound and a growth regulator including a predetermined terminal group and structure. In a thin film deposition process, by using the metal thin film precursor composition, side reactions may be suppressed and thin film growth rate may be controlled appropriately. Since process by-products in a thin film are removed, even when the thin film is formed on a substrate having a complicated structure, step coverage and the thickness uniformity and resistivity characteristics of the thin film may be greatly improved. In addition, corrosion or deterioration may be prevented, and the crystallinity of the thin film may be improved, thereby improving the electrical properties of the thin film.
