Apparatus and method for correcting position of laser beam for use in manufacturing biosensor with fine pattern

An apparatus for correcting a position of a laser beam to be used when manufacturing a biosensor having a fine pattern, the apparatus comprising:

• a loading unit with a surface on which an alignment mark is formed and on which a substrate is loaded;
• a laser beam generating unit that is positioned above the loading unit and generates a laser beam in a direction toward the surface of the loading unit to form an alignment mark and a fine pattern on the substrate;
• a vision unit that generates corrected coordinate values based on the alignment mark formed on the substrate, and a driving error of the laser beam generating unit;
• a position detector that is positioned at a lower end portion of a center portion of the loading unit and that detects information about the laser beam generated by the laser beam generating unit;
• and
• a controller that controls the laser beam generating unit according to the corrected coordinate values generated by the vision unit, and controls a power of the laser beam of the laser beam generating unit on the basis of the information detected by the position detector or controls a position of the loading unit.
