<h3>Overview</h3>
<p><strong>Topsil Series</strong> denotes high-purity synthetic sapphire substrates manufactured via the Edge-defined Film-fed Growth (EFG) or Kyropoulos process. These wafers feature exceptional thermal conductivity, electrical insulation, and optical transparency across UV to IR spectra.</p>
<h3>Application</h3>
<ul>
<li>Semiconductor: Substrates for GaN/AlGaN power electronics and RF devices.</li>
<li>Optoelectronics: LED epitaxial growth carriers and laser windows.</li>
<li>Aerospace: Infrared dome sensors and high-temperature optical windows.</li>
<li>Metrology: Precision reference surfaces for lithography systems.</li>
</ul>
<h3>Precautions</h3>
<ul>
<li>Operating Temperature: Continuous use up to 1200°C; rapid thermal cycling avoided.</li>
<li>Humidity Control: Storage below 60% RH to prevent surface hydrolysis.</li>
<li>Maintenance: Handle with diamond-coated tools only; clean using anhydrous solvents.</li>
</ul>
