Abstract
The disclosure relates to an apparatus for transferring a semiconductor die from an arrangement of semiconductor dies to a target and to a wafer stage to be used in such an apparatus. The wafer chuck includes a rotationally mounted curved shell on which the arrangement of semiconductor dies can be arranged, and the wafer stage includes a first motor for rotating the curved shell around a rotational axis. The curved configuration allows an improved throughput of the wafer stage. The film frame carrier used with this wafer stage comprises a ring-shaped body with an asymmetric bending stiffness allowing the ring-shaped body to be bent so that the mounting surface of the ring-shaped body changes from having a first shape to a second more concave shape and prevents or limits the ring-shaped body to be bent so that the shape of the mounting surface becomes more convex than the first shape.
