Latest Patents

Dongsheng Chen holds a patent for an "Apparatus and methods for optically inspecting a sample for anomalies." This patent discloses methods and apparatus for detecting a relatively wide dynamic range of intensity values from a beam, such as scattered light, reflected light, or secondary electrons, originating from a sample like a semiconductor wafer. The inspection system provides detected output signals with wide dynamic ranges, which can be analyzed to determine the presence of defects. The system includes a beam generator that directs an incident beam towards a sample surface and a detector that captures the detected beam originating from the sample surface. The detector features a sensor that generates a detected signal and a non-linear component that produces a non-linear detected signal. This innovation is crucial for improving the accuracy of defect detection in semiconductor manufacturing.
