Abstract:
A method for manufacturing an exposure apparatus which transfers a prescribed pattern on a first mask onto a prescribed area on a substrate by illuminating the prescribed pattern on the first mask using an ArF excimer laser or pulsed laser generated by a harmonic generator, the method comprising the steps of:providing a projection apparatus, which is arranged in the exposure apparatus, and that test exposes a predetermined pattern on a second mask onto an object to be illuminated using the ArF excimer laser or pulsed laser generated by the harmonic generator, providing a device electrically connected to the projection apparatus to cause the projection apparatus to test expose the predetermined pattern on the second mask onto a predetermined area on the object to be illuminated, the predetermined area on the object to be illuminated having a size different from that of the prescribed area; providing a device, which is electrically connected to the exposure apparatus, and that adjusts the exposure apparatus in accordance with a predetermined condition obtained through evaluating an image of the predetermined pattern test exposed onto the predetermined area on the object to be illuminated; providing a device that detects illuminance of an illumination area on the object to be illuminated before test exposing the predetermined pattern onto the predetermined area; and providing a device, which is electrically connected to the projection apparatus and the device that detects illuminance, and that calculates the degree of the unevenness of the illuminance based on a detection result of the device that detects illuminance, and allows execution of a test exposure operation by the projection apparatus for test exposing the predetermined pattern on the second mask onto the object to be illuminated when the degree of the unevenness of the illuminance is within an acceptable range.
