Abstract

PURPOSE: To eliminate exposure nonuniformity due to interference fringes produced in an exposed area on a wafer by providing a first rocking means which allows light entering a second optical integrator to be rocked at least one- dimensionally.
CONSTITUTION: A rocking means (a first scanning mirror-17, etc.) which allows light flux inciding a second optical integrator to be rocked at least in one direction (one dimension) is provided between a first-stage optical integrator (a fly eye lens 3, a single rod, or an optical fiber flux) and a second-stage optical integrator (a fly eye lens 5, etc.). Thus, the optical integrator is configures in two stages to allow illumination distribution on an object to be illuminated to be uniform and speckle pattern (interference fringe) to be smoothed satisfactorily by rocking a scanning mirror 17. It allows a uniform illumination light without any ghost, speckle, etc., to be obtained.
