Abstract:
An exposure apparatus is provided. An illumination optical system in the apparatus includes a diffraction optical element, a condensing optical system a detector that detects a light beam that exited from the condensing optical system, and a first diaphragm that can be inserted/removed in/from a position near a predetermined plane in an optical path where the condensing optical system condenses a light beam. The first diaphragm has an opening diameter such that an output of the detector decreases when an incident angle of light from a light source on the diffraction optical element deviates from a target angle. Based on an output of the detector when the first diaphragm is inserted in the position and an output of the detector when the first diaphragm is retracted from the position, a controller performs a process of adjusting the incident angle.

Claim (Index 15):
An article manufacturing method of manufacturing an article, the method comprising:\n exposing a substrate by using an exposure apparatus; and developing the substrate exposed in the exposing, wherein the exposure apparatus comprises: an illumination optical system configured to illuminate an original with light from a light source; a projection optical system configured to project a pattern of the original on a substrate; and a controller, wherein the illumination optical system includes a diffraction optical element provided in an optical path between the light source and the original, a condensing optical system configured to condense a light beam that exited from the diffraction optical element, a detector configured to detect a light beam that exited from the condensing optical system, and a diaphragm arranged in the optical path near a predetermined plane where the light beam is condensed by the condensing optical system and having an adjustable opening diameter, based on a first output as an output of the detector when the opening diameter of the diaphragm is set to a first opening diameter and a second output as an output of the detector when the opening diameter of the diaphragm is set to a second opening diameter larger than the first opening diameter, the controller is configured to perform a process of adjusting an incident angle of the light from the light source on the diffraction optical element, the first opening diameter is an opening diameter where an output of the detector decreases when the incident angle deviates from a target angle, and the second opening diameter is an opening diameter where the output of the detector does not decrease even when the incident angle deviates from the target angle.
