Abstract:
An exposure apparatus that forms a predetermined pattern on a substrate by using an exposing optical system, the exposure apparatus comprising:a main column that supports the exposing optical system; a first vibration isolator that supports the main column, the first vibration isolator being an active isolator; a first base member that supports the first vibration isolator, the first base member being mounted on a floor surface; a stage supporting member that supports a substrate stage that holds the substrate; a second vibration isolator that supports the stage supporting member; a second base member that supports the second vibration isolator, the second base member being mounted on the floor surface and being independent of the first base member; a column position measurement unit that measures a positional relationship between the first base member and the main column; and a controller that controls the first vibration isolator based on a measurement value of the column position measurement unit.
