Photoresist behaves the way the thermal budget tells it to—no exceptions. If the IR lamp is weak or inconsistent, you don’t get a do-over. You get line-width variation, scum, and scrap. You’re running 300 mm wafers through a tight loop—coat, bake, <a href="https://henruite.com">expose</a>, develop. The thermal profile has to repeat, wafer to wafer, lot to lot. When the lamp housing runs hot, the setpoint drifts. When the sleeve transmits unevenly, the edge sees a different temperature than the center. The tool can compensate, but the process window gets squeezed. A quartz sleeve for fab IR lamps isn’t a consumable you tolerate. It’s the interface between your heat source and your photoresist. It sets uniformity, repeatability, and uptime.</p>
