    摘要: The present invention is directed to an automated method of controlling critical dimensions of features by controlling the stepper exposure dose, and a system for accomplishing same. In one embodiment, the method comprises measuring a critical dimension (FICD) of a plurality of features formed in a process layer, and providing the measured critical dimensions of the features to a controller that determines, based upon the measured critical dimensions, an exposure dose of an exposure process to be performed on at least one subsequently processed wafer. In another embodiment, the method comprises measuring a critical dimension (DICD) of a plurality of features formed in a patterned layer of photoresist, providing the measured critical dimensions of the features in the patterned layer of photoresist to a controller that determines, based upon the measured critical dimensions, an exposure dose of an exposure process to be performed on at least one subsequently processed wafer. In some embodiments, both the FICD measurements and the DICD measurements are used to determine the exposure dose.
