Abstract
A system for flipping a semiconductor workpiece on its thin edge for microscope inspection of a workpiece facet is disclosed. The system has a holding device attached to a handling block. The holding device picks a workpiece by one of its thin edges. The edge of the workpiece may be attached to the holding device by vacuum. Then an operator rotates the handling block ninety degrees, which in turn rotates the holding device and workpiece ninety degrees. After rotation, one of the workpiece facets faces upward and perpendicular to the microscope for proper inspection of the facet.
