Gigaphoton’s Two Representatives Achieved Awards in the 61st National Skills Competition


<p>We would like to express our heartfelt sympathy to the affected people due to the earthquake that occurred on January 1st at Noto Peninsula, Ishikawa, Japan.</p>



<p>Following the earthquake, Gigaphoton has been prioritizing the safety of our employees and carrying out activities such as employee safety confirmation, information gathering regarding factory buildings, and collaborating with partner companies. Through these efforts, we have confirmed that all employees are safe and our factory operations and customer support can continue as usual.</p>



<p>Our situation is as follows:</p>



<ul class="wp-block-list">
<li>We have confirmed the safety of all our employees.</li>



<li>No damage has been reported at our production facilities, as Oyama City, Tochigi Prefecture, experienced an earthquake with a seismic intensity of 3(which is significantly smaller compared to a seismic intensity of 7).<br>As scheduled, we started production activities on January 8th.</li>



<li>Our customer support operations are unaffected, as there are no issues with the stored inventory of completed systems and parts in our warehouse and we have spare inventory at support bases nationwide.</li>



<li>We are currently investigating the impact on our supply chain.</li>
</ul>

<p class="has-text-align-center">G300K, a KrF excimer laser for ultra-fine ablation processing</p>



<p>Gigaphoton has applied its expertise in semiconductor lithography lightsources to develop a lightsource for ultra-fine ablation processing for advanced packaging processes.</p>



<p>The latest addition to its lineup, the G300K, is an excimer laser based on KrF (248nm) wavelength, which is connected to the processing equipment for semiconductor package substrates. It achieves high power, high repetition rate, high uptime, and long lifespan.&nbsp;&nbsp; The excimer laser is primarily used in the process of creating small holes with a diameter of 10μm or less, as well as trenches. It is expected to be adopted for the manufacturing of 2.5D/3D packages utilizing chiplets, which are projected to increase primarily for server applications.</p>



<p>Katsumi Uranaka, President and CEO of Gigaphoton said, &#8220;In Gigaphoton, alongside our research and development of lightsources for semiconductor lithography, we have also been exploring various possibilities for the application of excimer lasers in other fields. Through this journey, our product, the G300K, has been integrated into ORC MANUFACTURING&#8217;s equipment and installed for the first time in the semiconductor package substrate industry. We have faced numerous challenges along the way, but we are delighted with this installation. As a critical lightsource manufacturer in the semiconductor manufacturing industry, we will continue to contribute to the industry through continuous research and development on new processes to facilitate the further implementation of excimer lasers.</p>

<p>In February 2023, Gigaphoton installed 1,100 photovoltaic panels on the roof of its head office building and is scheduled to begin power generation in May. The installed solar panels are expected to generate approximately 460MWh per year (equivalent to approximately 4% of the annual power consumed by Gigaphoton), which is equivalent to approximately 210t-CO2 <sup>*1</sup> in terms of CO2 emissions.</p>



<p>Gigaphoton also designed the new production building, that is currently under construction (scheduled for completion in late 2023), with the installation of solar panels to increase the ratio of renewable energy used. Gigaphoton aims to be carbon neutral by virtually eliminating its own GHG emissions in 2030. One of the efforts toward carbon neutrality is the aim of achieving a 30% use ratio of renewable energy in 2030. To achieve this goal, Gigaphoton will promote energy creation, including installation of solar panels, in parallel with power saving in production processes and other areas.</p>



<p>Katsumi Uranaka, President and CEO of Gigaphoton said, &#8220;Based on our sustainability policy, Gigaphoton will further accelerate the reduction of power consumption during product operation, while actively working to reduce GHG generated during production by reducing power consumption during production and utilizing renewable energy. As a supplier of lithography lightsources essential for semiconductor manufacturing, we will proactively contribute to reducing environmental impact through a wide range of initiatives.</p>
