Patent ID: 6898007

Claim:
A microscope for inspecting a semiconductor wafer, comprising: an optical unit including objective lenses and oculars for observing the semiconductor wafer; a display unit for magnifying and displaying an image of the semiconductor wafer observed by the optical unit; a sample piece stage holding the semiconductor wafer and including at least two wafer stoppers at a radius distance of a round portion of the semiconductor wafer from a central pivot of the semiconductor wafer; a stage moving unit for moving the semiconductor wafer in an x-axis direction, a y-axis direction and/or a z-axis direction; a stage rotation unit for rotating the semiconductor wafer in a horizontal direction; a stage tilting unit for rotating an end of the sample piece stage to tilt the semiconductor wafer from 0° to 180°, wherein the stage tilting unit is displaceable in an x-y-z direction by the stage moving unit; and a controller for controlling operation of the microscope.
