Abstract:
An extreme ultraviolet light (EUV) generation system is configured to improve conversion efficiency of energy of a laser system to EUV energy by improving the efficiency of plasma generation. The EUV generation system includes a target generation unit configured to output a target toward a plasma generation region in a chamber. The laser system is configured to generate a first pre-pulse laser beam, a second pre-pulse laser beam, and a main pulse laser beam so that the target is irradiated with the first pre-pulse laser beam, the second pre-pulse laser beam, and the main pulse laser beam in this order. In addition, the EUV generation system includes a controller configured to control the laser system so that a fluence of the second pre-pulse laser beam is equal to or higher than 1 J/cm 2  and equal to or lower than a fluence of the main pulse laser beam.

Claim (Index 5):
The extreme ultraviolet light generation system according to  claim 1 , wherein the laser system includes:\n a first pre-pulse laser apparatus configured to generate the first pre-pulse laser beam; a second pre-pulse laser apparatus configured to generate the second pre-pulse laser beam; and a main pulse laser apparatus configured to generate the main pulse laser beam.
