Abstract:
The invention relates to a method for correcting the critical dimension uniformity of a photomask for semiconductor lithography, comprising the following steps: determining a transfer coefficient as a calibration parameter, correcting the photomask by writing pixel fields, verifying the photomask corrected thus, wherein a transfer coefficient is used for verifying the corrected photomask, said transfer coefficient being obtained from a measured scattering function of pixel fields.

Claim (Index 1):
A method for correcting the critical dimension uniformity (CDU) of a photomask for semiconductor lithography, the method comprising the following steps:\n determining a CDU to be corrected by way of a scanner-equivalent CDU measurement, determining a transfer coefficient as a calibration parameter, correcting the photomask by writing pixel fields, verifying the photomask corrected thus, wherein the transfer coefficient is used for verifying the corrected photomask, said transfer coefficient being obtained from a scattering function of pixel fields measured in advance.
