Claim:
1. An exposure apparatus, comprising: a light source configured to provide a light in accordance with a pulse event generation (PEG) representing a period of light radiation; an illuminating member configured to change the light into point lights; a projecting member configured to project the point lights according to a photoresist shape extending in various directions; a stage on which the point lights are projected; an inspecting member configured to inspect a photoresist pattern formed by the projected point lights; and an information processing member configured to analyze different photoresist patterns corresponding to different PEGs, to select one PEG from the different PEGs, the one PEG being associated with a minimum error in the various directions, wherein the information processing member is configured to select the one PEG based on the following equation: LE represents a line edge length of the photoresist pattern, n represents an integer, and ΔY represents a radiating interval of the light.
