The line won’t swallow a ±0.5 °C swing, and the cleanroom won’t tolerate extra particles. If the thermal profile drifts even a little, you lose CD control—and you lose yield.</p> <h2 id="infrared-heating-accuracy-sub-millimeter-uniformity-and-repeatability">Infrared heating accuracy: sub-millimeter uniformity and repeatability</h2> <p>The DNS screen wafer dryer lamp is built around short-wave infrared emitters tuned to how common photoresist stacks absorb. That gives you sub-millimeter thermal uniformity across the wafer plane, and repeatable setpoint tracking that keeps temperature inside tight tolerances during both soft bake and hard bake. Closed-loop control locks the thermal budget right where the recipe calls for it, so every lot sees the same profile, shift after shift.</p>
