Soft bake at 90 °C, hard bake at 110 °C. The photoresist has to behave the same way, lot after lot. When the thermal profile drifts, you pay for it on the spot: CD shift, poor adhesion, bridge defects—then rework. The heater isn’t just another box in the background. It’s the control knob on the photoresist thermal budget. Optical wafer processing heaters are built for that control. They deliver fast, low-contact or non-contact heating with tight uniformity and repeatability, so the bake step doesn’t turn into a source of variability.</p>
