Patent ID: 7806076

Claim:
A developing apparatus for developing a substrate whose surface is coated with a coating solution and then exposed, the apparatus comprising: a substrate supporting unit to slantingly support the substrate at an inclined angle; a rotation driving mechanism to rotate the substrate supporting unit with respect to a perpendicular axis; a developer nozzle, disposed to face a surface of the substrate supported by the substrate supporting unit, having a strip-shaped injection opening extended along a direction extending from a periphery of the substrate toward a central portion thereof; a moving unit to move the developer nozzle from an outer portion of the substrate toward the central portion thereof; a guide unit to support the moving unit, the guide unit being inclined at an angle that is equal to the inclined angle of the substrate such that the moving unit slidably moves the developer nozzle in parallel with the surface of the substrate while the substrate is rotated forwardly by the rotation driving mechanism; and a controller to control operations such that while the substrate is rotated forwardly by the rotation driving mechanism, a developer is supplied through the injection opening to the surface of the substrate by moving the developer nozzle.
