Abstract:
A method and extreme ultraviolet (EUV) light source including a laser source configured to generate a first pre-pulse laser beam, a second pre-pulse laser beam, and a main pulse laser beam. In some embodiments, a droplet is irradiated within an extreme ultraviolet (EUV) vessel using the first pre-pulse laser beam to form a re-shaped droplet. In some examples, the droplet includes a tin droplet. In various embodiments, a seed plasma is then formed by irradiating the re-shaped droplet using the second pre-pulse laser beam. Thereafter, and in some cases, the seed plasma is heated by irradiating the seed plasma using the main pulse laser beam to generate EUV light.

Claim (Index 9):
The method of  claim 1 , wherein the second pre-pulse laser beam is implemented as one of a single pulse and a pulse train.
