Photoresist profiles shift, critical dimensions open up, and the line starts chasing excursions instead of running them. In coater/developer tracks, the <a href="https://henruite.com">thermal</a> step is where repeatability either holds together or falls apart.</p> <h2 id="infrared-heating-precision-sub-millimeter-uniformity-and-repeatability">Infrared Heating Precision: Sub-Millimeter Uniformity and Repeatability</h2> <p>We built the coater/developer infrared heater around a short-wave NIR design with engineered radiant distribution. The payoff is a thermal field with sub-millimeter uniformity across the wafer plane, giving you wafer-level temperature control inside tight tolerance. Repeatability comes from closed-loop calibration and stable emissivity management, so every bake lands the same way—batch after batch, shift after shift. This isn&rsquo;t about hitting peak temperature; it&rsquo;s about controlling the full thermal budget the resist sees.</p>
