  • 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.

  • Publication number: 20240383927
    Abstract: A silicon precursor compound, a preparation method therefor, a silicon-containing film formation composition containing the silicon precursor compound are disclosed. A method for forming a silicon-containing film by using the silicon-containing film formation composition is also disclosed. The silicon-containing film formation composition contains a silicon precursor compound having a specific structure so that the thickness of a silicon-containing film can be controlled to be very thin through atomic layer deposition (ALD), and, when a silicon-containing composite film is formed by combining an ALD cycle that forms a silicon-containing film and an ALD cycle that forms a film containing another metal, the silicon amount of the silicon-containing composite film can be finely controlled to be in a low range.
