A susceptor includes a plurality of holes in a first area and a plurality of holes in a second area. The first and second areas overlap a location which corresponds to at least one portion of a semiconductor device to be processed. The holes in the first area are provided in a first pattern and the holes in the second area are provided in a second pattern which may be different from the second pattern. The first and second patterns may differ, for example, based on the size, arrangement, spacing, location, and/or density of the holes. |
