The real fight is against particles. If you&rsquo;re working in a Class 100 cleanroom, you already know the nightmare: one tiny flake of degraded filament or a bit of outgassing material, and your entire batch is trash. That&rsquo;s why we stick with high-purity synthetic quartz infrared lamps. They just work.</p> <h2 id="why-the-quartz-matters">Why the Quartz Matters</h2> <p>Most standard quartz has impurities. When things get hot, those impurities break down and spit micro-particles right into your airflow. Not great. We use high-purity fused silica instead. It doesn&rsquo;t crystallize or &ldquo;shed&rdquo; when you&rsquo;re cycling the heat up and down rapidly. It stays put. The way it works is pretty cool. The infrared radiation hits the liquid film on the wafer and evaporates it almost instantly. Since we&rsquo;re using a short-wave spectrum, the energy goes straight to the water. You don&rsquo;t have to bake your entire chamber just to get a wafer dry.</p>
