Abstract:
A method and apparatus for hybrid test pattern generation for optical proximity correction (OPC) model calibration is disclosed. Embodiments may include receiving a mask pattern of a chip layout, extracting one or more patterns from the mask pattern, determining one or more parametric data sets for the one or more patterns, retrieving one or more calibration parametric data sets based on one or more other mask patterns, determining a difference between the one or more parametric data sets and the one or more calibration parametric data sets, and adding the one or more parametric data sets to the one or more calibration parametric data sets if the difference satisfies a threshold value.
