Abstract
A method for manufacturing a semiconductor device comprises the steps of extracting an optimal working condition by accumulatively averaging accumulated working conditions of lots previously performed in an expectation process to be currently performed in the manufacturing equipment, extracting a correction condition by extracting information for an alignment state of a lower layer performed by the expectation process, and setting the working condition by adding the correction condition to the optimal working condition.
