In accordance with a first aspect, a susceptor is provided that includes (1) a supporting surface adapted to support a substrate, the supporting surface comprising a first material; and (2) a support frame encased within the first material, the support frame comprising a second material that has a lower coefficient of thermal expansion than the first material. The support frame is offset from a center of the susceptor toward the supporting surface. In accordance with a second aspect, a susceptor is provided that includes (1) a supporting surface adapted to support a substrate, the supporting surface comprising a first material; and (2) a support frame encased within the first material, the support frame comprising a second material that has a higher coefficient of thermal expansion than the first material. The support frame is offset from a center of the susceptor away from the supporting surface. Other aspects are also provided.
