<h2 class="wp-block-heading">An ArF Excimer Laser that Contributes to Productivity Improvements, for Immersion Exposure Devices Intended for Sub-10nm Nodes.</h2>



<p>GT65A, the seventh generation of platforms using the injection lock method, is installed with leading-edge technology and achieves further improved productivity (wafer output) for the customer through “exposure performance improvements” due to changeable spectral width (E95) and improved stability, “high availability” due to extended module lifespan and “reduced environmental load” as it is helium free.</p>

<h4 class="wp-block-heading">Changeable spectral width (E95)</h4>



<p>The spectral width can be modified in order to suit various customer requirements and uses. For example, the spectral width can compensate for contrast performance variations in different generations of exposure devices. Also, it is possible to match OPC characteristics between equipment or between masks due to the changeable spectral width functionality*<sup>1</sup><br>*1) This functionality varies according to the connected exposure device.</p>



<h4 class="wp-block-heading">Improved spectral width (E95) stability</h4>



<p>The spectral width control speed has been successfully increased to 20 times that of previous equipment. This ensures that the spectral width is more stable during equipment operation and allows for a reduction in critical dimension errors.</p>



<h4 class="wp-block-heading">Extended module lifespan</h4>



<p>By extending the main module lifespan, the maintenance frequency has been decreased even further. This makes it possible to operate the equipment for extended periods of time.</p>



<h4 class="wp-block-heading">Helium free</h4>



<p>Technology that uses zero helium for ArF excimer laser operation is installed. This contributes to a reduction in customer costs and a reduced environmental load.</p>

<h3 class="wp-block-heading">GT63A Main Features &#8211;&nbsp;Four “s” Series Functions</h3>



<h4 class="wp-block-heading">sMPL</h4>



<p>The sMPL technology for focus drilling increases laser spectrum control width to a level 10 times that of conventional technology, thus creating a greater depth of focus. Focus drilling enables expansion of the lithography process window for contact holes, trenches and vias that is not possible with conventional technology, while avoiding negative effects on critical dimension uniformity (CDU), overlay and productivity. The sMPL technology was tested in a high-volume manufacturing environment in partnership with a leading scanner manufacturer and device manufacturer.</p>



<h4 class="wp-block-heading">sGRYCOS</h4>



<p>The enhanced sGRYCOS technology extends the effective life of a laser chamber — one of the main consumable components of an excimer laser — to 1.5 times longer than any conventional chamber today, offering world-class endurance that significantly reduces factory operating costs. This durability results from increasing the strength of the pre-ionization &nbsp;in a newly developed chamber and uses a robust pulse-power supply for today’s and tomorrow’s power requirements.</p>



<h4 class="wp-block-heading">sTGM</h4>



<p>The sTGM technology implements an innovative wavelength calibration method to eliminate the previous need to routinely replace the laser chamber’s gas. This new industry standard completely eliminates wasted process gases based on calibration requirements, thereby measurably reducing facility costs and improving laser availability on an annual basis. This unique gas management technology allows for system calibration of laser wavelength “as-is” without replacement of the laser chamber’s gas, a first-of-its-kind capability.</p>



<h4 class="wp-block-heading">sMONITORING</h4>



<p>The sMONITORING technology, an extension of existing real-time monitoring of laser performance, can be connected with the end-user’s FDC (Fault Detection and Classification) system to monitor system operation. It is a final check on highly stable laser output to the scanner and on-wafer performance.</p>

The design concept and reliability of the GT40A are highly acclaimed in the industry, and because the GT60A is based on the same platform to maximize standardization as well as enable the use of common components, thereby ensuring users to achieve high reliability right from the onset.</p>

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



<h4 class="wp-block-heading"><strong><strong><strong><strong><strong>High Output and High Repetition Rate</strong></strong></strong></strong></strong></h4>



<p>Improving on the GT40A, which achieved a repetition rate of 4,000 Hz, the GT60A reaches a repetition rate of 6,000 Hz on the same platform through greatly enhanced efficiency. This improvement enables an output level of that is more than 33% higher than the GT40A, while limiting the energy per pulse. While the GT60A features output and repetition frequency enhancements, the laser’s spectral performance supports the resolution of lithography tools at the same level as the GT40A.</p>



<h4 class="wp-block-heading"><strong><strong><strong><strong>High Reliability and High Stability</strong></strong></strong></strong></h4>



<p>The GT60A leverages the same platform as that of the GT40A—maximizing standardization as well as enabling the use of common components for ensuring high reliability. In addition to its advanced self-diagnostic function, the GT60A features a variety of functions to enhance system availability. One of the major advantages of the GT series is the ease of module replacement and serviceability, which ensures the high reliability and high uptime essential in today’s semiconductor fabs.</p>
