That’s a whole lot of scrap in a hurry. We built the infrared lamp with an air knife unit to keep the thermal line where it has to be—on the wafer, across the field, shift after shift.</p> <h2 id="infrared-heating-precision-sub-millimeter-uniformity-and-repeatability">Infrared heating precision: sub-millimeter <a href="https://henruite.com">uniformity</a> and repeatability</h2> <p>The system leans on short-wave NIR emitters to dump energy straight into the photoresist, fast. Closed-loop control holds the setpoint within ±0.1°C. The quartz-based design keeps the thermal profile stable and repeatable, and sub-millimeter uniformity across the wafer cuts edge bead and sharpens pattern fidelity. The integrated air knife throws a laminar, high-velocity curtain across the surface. It strips moisture and particles without touching the wafer, so you can run in Class 1–100 cleanrooms and keep particle counts down.</p>
