Compensation frame for holding substrate for semiconducting manufacture has polygonal inner profile for holding substrate, area of upper main surface of frame with different widths at different points

摘要

The frame (2) has an inner contour for holding a substrate (1), a region (3a) of an upper main surface at a defined height above the substrate in the frame and a further region (3b) at essentially the same height as the plane of the upper main surface (1a) of the substrate in the frame. The inner profile is polygonal for accommodating the substrate and the further area of the upper main surface of the frame has different widths at different points.
