Latest Patents

Seungju Chun holds a patent for a substrate processing method. This method involves providing a substrate into a reaction space, where the substrate features a gap with a predetermined cross-sectional area and depth. The process includes a first sub-cycle step for depositing a gap-filling material by a predetermined thickness along the surface of the gap using an atomic layer deposition method. Additionally, a second sub-cycle step is performed to form a deposition inhibiting region in the upper part of the gap using a deposition inhibitor. The super-cycle is repeated to ensure that the cross-sectional area of the inlet region of the gap remains greater than that of the lower region, allowing the gap to be filled without the occurrence of voids.
