EUV IN-SITU LINEARITY CALIBRATION FOR TDI IMAGE SENSORS USING TEST PHOTOMASKS
A photomask includes a plurality of distinctly patterned regions to provide different respective intensities of extreme ultraviolet (EUV) light in response to illumination with an EUV beam. The photomask may be part of a system that also includes a time-delay-integration (TDI) inspection tool with a...

| description | A photomask includes a plurality of distinctly patterned regions to provide different respective intensities of extreme ultraviolet (EUV) light in response to illumination with an EUV beam. The photomask may be part of a system that also includes a time-delay-integration (TDI) inspection tool with an EUV light source and a TDI sensor. The EUV light source is to generate the EUV beam. The photomask is to be loaded into the TDI inspection tool. The system further includes a reference intensity detector to be mounted in the TDI inspection tool to measure intensities of EUV light collected from the photomask. |
