摘要

LITHOGRAPHIC APPARATUS AND DEVICE MANUFACTURING METHOD USING MULTIPLE EXPOSURES AND MULTIPLE EXPOSURE TYPES A lithographic apparatus and method in which a relatively high resolution exposure, for example of a repeating pattern, is trimmed using a relatively low resolution exposure. According, a compromise between provision of a high resolution pattern and flexibility in the pattern to be formed is provided. Figure 14b
