  • Publication number: 20240093369
    Abstract: A deposition apparatus includes a chamber providing an inner space, a gate disposed on one side of the chamber and opening and closing the chamber to allow a substrate to be loaded and unloaded therethrough, and a susceptor including one surface on which the substrate is seated. The susceptor includes a susceptor body including a first region and a second region disposed in a first direction farther away from the gate than the first region, a first hot-wire arranged in a first pattern in the first region, and a second hot-wire arranged in a second pattern in the first and second regions. The first and second hot-wires is asymmetric with respect to a second direction crossing the center of the susceptor body in a plan view and orthogonal to the first direction, and the first and second hot-wires may be controlled independently.
