Semiconductor inter-field dose correction

A method and apparatus are provided for adapting a semiconductor inter-field dose correction map from a first photolithography mask to a second photolithography mask using the same manufacturing stack and reactive ion etching processes, the method including: obtaining a first dose correction map for the first photolithography mask as a function of first chip or die identities; determining a first transformation matrix from the first chip or die identities of the first photolithography mask into an orthogonal coordinate system; determining a second transformation matrix from second chip or die identities of the second photolithography mask into the orthogonal coordinate system; and transforming the first dose correction map for the first photolithography mask into a second dose correction map for the second photolithography mask in correspondence with each of the first and second transformation matrices.
