Abstract
In accordance with some embodiments, a lithography method in semiconductor manufacturing is provided. The lithography method includes transmitting a main pulse laser to a zone of excitation through a first optic assembly. The lithography method further includes supplying a coolant to the first optic assembly and detecting a temperature of the coolant with a use of at least one sensor. The lithography method also includes adjusting a heat transfer rate between the coolant and the first optic assembly based on the temperature of the first optic assembly. In addition, the lithography method includes generating a droplet of a target material into the zone of excitation. The lithography method further includes exciting the droplet of the target material into plasma with the main pulse laser in the zone of excitation.
