摘要:
An exposure apparatus for exposing a substrate to radiant energy includes: a stage including a chuck, and configured to hold the substrate on the chuck with vacuum and to be moved; a recovery device configured to recover the substrate from the stage; a first detector configured to detect an error of holding of the substrate on the chuck; a measuring device configured to measure an amount of positional deviation of the substrate relative to the chuck; and a controller configured to cause the measuring device to measure the amount of positional deviation in a case where the first detector detects the error, and to control an operation of the stage such that the amount of positional deviation falls within a tolerance based on the measured amount.
