    摘要: A method for patterning a wafer includes performing a first patterning on a wafer, and after performing the first patterning, calculating a simulated dose mapper (DoMa) map predicting a change in critical dimensions of the wafer due to performing a second patterning on the wafer. The method further includes performing the second patterning on the wafer. Performing the second patterning includes adjusting one or more etching parameters of the second patterning in accordance with differences between the simulated DoMa map and desired critical dimensions of the wafer.
