Abstract:
A radiation source apparatus is provided. The radiation source apparatus includes a chamber, a target droplet generator, an exhaust module, a measuring device, and a controller. The target droplet generator is configured to provide a plurality of target droplets to the chamber. The exhaust module is configured to extract debris corresponding to the target droplets out of the chamber according to a first gas flow rate. The measuring device is configured to measure concentration of the debris in the chamber. The controller is configured to adjust the first gas flow rate according to the measured concentration of the debris.

Claim (Index 8):
An extreme ultraviolet (EUV) lithography system, comprising:\n an EUV scanner configured to perform a lithography exposure process in response to EUV radiation; a light source configured to provide the EUV radiation to the EUV scanner, wherein the light source comprises:\n a chamber; \n a collector configured to collect the EUV radiation and direct the EUV radiation to the EUV scanner in the chamber; \n a target droplet generator configured to provide a plurality of target droplets to the chamber; \n a measuring device configured to measure concentration of debris corresponding to the target droplets in the chamber; and \n a controller configured to adjust a first gas flow rate according to the measured concentration of the debris and a control signal from the EUV scanner, so as to perform a purge operation in the chamber; and \n an exhaust module configured to extract the debris out of the chamber according to the first gas flow rate, wherein the control signal indicates the lithography exposure process is completed.
