Abstract
A wafer measurement stage for supporting a semiconductor wafer for surface geometry measurements. The wafer measurement stage includes a support body having a planar surface configured to face a wafer which is supported by the wafer measurement stage, and a wafer contact structure provided on the planar surface. The wafer contact structure is configured to contact a portion of a wafer such that the wafer is supported in an elevated position relative to the planar surface and to control gravity effects at non-contact portions of the wafer.
