Patent ID: 6897422

Claim:
A measuring configuration for measuring a semiconductor wafer having at least one feature with a critical dimension, comprising: a scanning electron microscope for measuring the critical dimension of the at least one feature of the semiconductor wafer; at least one measuring device for an angle-dependent measuring of one of a scattering and a diffraction of light at the at least one feature of the semiconductor wafer; at least one loading and unloading station for loading and unloading wafer transport containers receiving the semiconductor wafer; a transport system for transporting the semiconductor wafer, said transport system having transport paths including at least a respective transport path between said at least one loading and unloading station and said scanning electron microscope, and between said at least one loading and unloading station and said at least one measuring device for an angle-dependent measuring of one of a scattering and a diffraction of light; and a control unit operatively connected to said transport system, said control unit selecting and controlling one of said transport paths of said transport system in order to selectively make the semiconductor wafer available to said at least one measuring device for an angle-dependent measuring of one of a scattering and a diffraction of light and to said scanning electron microscope.
