<p>Stability and durability are the biggest technological challenges for an excimer laser, because it uses fluorine, high-voltage discharge, and deep UV, all of which are highly reactive. As well as stability and durability, an excimer laser light source for lithography tools requires high monochromaticity for the laser beam and high uniformity for the output energy.<br>As the world’s first excimer laser light source that satisfies all of these requirements, the G10K has earned a top reputation in the lithography light source market since it was marketed in 1997. This model is still operating in the field world wide.</p>

<h2 class="wp-block-heading">A KrF Lithography Light Source That Achieves a High Output 150% Greater Than the Previous Model to Meet the Output Demands of Tomorrow</h2>



<p>Based on our KrF light source technology that is the result of many years of technological evolution and accumulated experience, the KrF lithography light source, G60K, which supports a scanner throughput of at least 300 wafers per hour, offers an output 150% greater than the previous model. Also, by extending the module’s lifespan by 200%, the G60K delivers improvements in terms of availability as well. A newly developed power supply and module see the G60K support performance improvements such as higher frequencies in preparation for the higher outputs of tomorrow to meet the demands of KrF lithography technology in the years to come. Helium-free technology is also installed as standard, meaning the G60K also contributes to reducing the energy consumption of utilities.</p>
