<p>There is provided a susceptor for a vapor phase epitaxial growth device, by which skidding at the time of loading a silicon wafer is prevented and the wafer can be loaded at a fixed position of the susceptor: wherein a ring-shaped groove having sloping planes widening toward a surface of the susceptor are formed on the outermost circumference of the bottom surface; and gas release openings penetrating through to the back surface of the susceptor are formed, each having a sectional area of 2.0 to 3.0mm 2 and a ratio of all opening areas is 0.25 to 0.5% on the bottom surface.</p> |
