Soft bake and hard bake temperatures that drift even a fraction can tilt the photoresist profile, throw off critical dimension control, and send yield out the window. When your coater/developer line is running 7×24, thermal stability isn&rsquo;t a “nice to have.” It&rsquo;s the constraint that keeps the fab honest.</p> <h2 id="what-actually-matters-technically">What actually matters, technically</h2> <p>We built the coater/developer infrared heater around short-wave NIR sources—fast response, tight thermal control. The target is wafer-level uniformity of ±0.1°C, so photoresist bake stability holds across the entire bake window. That’s what keeps line-to-line and lot-to-lot behavior from wandering. The heater is compatible with Class 1–100 cleanrooms and generates zero particles, which keeps contamination counts where they need to be: off the wafer surface.</p>
