  • Publication number: 20250109496
    Abstract: A film depositing composition including a Group 4 metal element-containing precursor compound and a method for forming a Group 4 metal element-containing film using same is described. The use of the film depositing composition including a Group 4 metal element-containing precursor compound achieves self-limiting film growth of ALD over a wide temperature range from low to high temperatures, enabling the formation of a Group 4 metal element-containing film for various purposes at various process temperatures. Particularly, according to the method for forming a Group 4 metal element-containing film of this invention, the growth per cycle (GPC) of ALD is consistent over a broad temperature range, thus making it possible to form a Group 4 metal element-containing film of uniform thickness even on surfaces with large aspect ratio trenches. Thus, the method can be advantageously utilized in manufacturing various semiconductor devices, such as DRAM, 3D NAND flash memory, and the like.
