Abstract
Disclosed is a wafer susceptor. A groove bottom of the wafer susceptor is divided by a first dividing line passing through a center of a groove into a first region close to a center of the wafer susceptor and a second region away from the center of the wafer susceptor. The groove bottom includes a groove bottom surface and a convex structure formed on the groove bottom surface. An average height of the convex structure located in the second region is greater than that of the convex structure located in the first region. A design structure of the groove bottom of the wafer susceptor well matches a warped III-V group nitride wafer in an active region epitaxial process.
