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 10):
The method according to  claim 3 , wherein the different illumination schemes for a mask metrology device and a scanner are taken into account when determining the transfer coefficient.
