<h2 class="wp-block-heading">4-kHz ArF Excimer Laser for 65-nm or below Technology Node</h2>



<p>Model GT40A uses an injection-locking resonator (first in the world) as a lithography tool light source to allow simultaneous maintenance of narrower spectral bandwidth and higher output, a combination that is difficult to achieve with conventional technologies. In addition, it provides lower peak-pulse energy that reduces damage to the lithography tool optics to achieve the lowest running cost in the industry. Model GT40A is also equipped with the newly developed advanced self-diagnosis function as well as it has greatly improved its serviceability such as the ease of module replacement to achieve higher reliability and higher uptime.</p>

<h3 class="wp-block-heading">Key Features</h3>



<h4 class="wp-block-heading">An injection-locking laser</h4>



<p>The GT40A is the industry’s first mass-production model to use <i>injection-locking</i> technology. This ensures highly stable emission of a DUV beam with high output of 45 W and a spectral bandwidth of 0.2 picometer (pm) for FWHM and 0.5 picometer for E95 — the highest bandwidth level in the industry. It also provides lower peak-pulse energy that reduces damages to the lithography tool optics.</p>



<figure class="wp-block-table is-style-regular"><table><tbody><tr><td><strong>Injection-locking</strong> technology injects a low-output laser beam (master), which is emitted after bring tuned to an extremely narrow spectral bandwidth, into a laser resonator (amplifier) that amplifies it with laser resonation. This technology allows simultaneous maintenance of a narrower spectral bandwidth and higher output, a combination that is difficult to achieve with conventional technologies.</td></tr></tbody></table></figure>



<h4 class="wp-block-heading">The industry&#8217;s lowest running cost</h4>



<p>The injection-locking technology allows greater reduction of the load upon the laser optics. Furthermore, the system configuration has been refined to significantly reduce both the number of consumables (modules) and their replacement frequency. As a result, the GT40A can achieve the lowest running cost in the industry.</p>



<h4 class="wp-block-heading">A highly reliable/operable design</h4>



<p>The high reliability and high uptime essential to semiconductor factories are achieved by introduction of a newly developed self-diagnosis function and great improvement in the ease of module replacement and serviceability.</p>
