Abstract: A method of inspecting an extreme ultraviolet (EUV) radiation source includes, in an idle mode, inserting a borescope mounted on a fixture through a first opening into a chamber of the EUV radiation source. The borescope includes a connection cable attached at a first end to a camera. The EUV radiation source includes an excitation laser that generates a light beam that is configured to focus onto tin droplets to generate EUV radiation inside the chamber of the EUV radiation source.
