Abstract
Embodiments described provide dynamic imaging systems that compensates for pattern defects resulting from distortion caused by warpage of the substrate. The methods and apparatus described are useful to create compensated exposure patterns. The dynamic imaging system includes an inspection system configured to provide 3D profile measurements and die shift measurements of the first substrate to the interface configured to provide compensated pattern data to the digital lithography system configured to receive the compensated pattern data from the interface and expose the photoresist with a compensated pattern.
