    摘要: The present disclosure provides a method of inspecting a photolithographic mask wherein a design database is received, and a feature of the design database is adjusted by a bias factor to produce a biased database. Image rendering is performed on the biased database to produce a biased image. A mask is also created using the design database, and the mask is imaged to produce a mask image. The biased image is compared to the mask image, and a new value for the bias factor may be determined based on the comparison.

    摘要: The present disclosure provides for many different embodiments. An exemplary method can include providing a mask fabricated according to a design pattern; extracting a mask pattern from the mask; converting the mask pattern into a rendered mask pattern, wherein the simulated design pattern includes the design pattern and any defects in the mask; simulating a lithography process using the rendered mask pattern to create a virtual wafer pattern; and determining whether any defects in the mask are critical based on the virtual wafer pattern. The critical defects in the mask can be repaired.
