Abstract

A light source apparatus according to an embodiment may be used for an exposure apparatus which exposes a plurality of wafers by repeating a wafer exposure for exposing a total exposure area of each wafer. The wafer exposure may include a sequential execution of scanning exposures in which each divided area defined by dividing the total exposure area of each wafer is scanned by pulsed light. The apparatus may comprise: a light source controller configured to execute a control for outputting the pulsed light based on a luminescence trigger signal received from the exposure apparatus; a detector configured to detect a characteristic of the pulsed light; and a data collection processor configured to collect at least a piece of data in data included in a pulse light data group related to the pulsed light detected by the detector and a control data group related to the control, and execute a mapping process of mapping the collected data by at least one of scanning exposure basis and wafer exposure basis.
