A 300 mm wafer flows from coat to soft bake, then into exposure, and the thermal budget you set in those first minutes writes the rules for CD uniformity, sidewall angle, and—bottom line—yield. When the bake lamp starts to drift, throws hotspots across the field, or fails outright, the line stops, the queue backs up, and your cost per wafer climbs before the first pattern is even written. Polyimide bake comes down to repeatable heat. You have to drive the resin into the right Tg window without solvent burst, without <a href="https://o-yate.net">skinning</a>, and without adding particles. Infrared can deliver that control—fast and stable—but only if the emitter, optics, and control loop are treated as one thermal system, not a box with a heater bolted on.</p>
