On the OLED line, drying isn’t a pause. It’s a control point. Wafers come out of rinse and need a stable surface before lithography. Under-dry the photoresist and you get edge bead, then overlay starts drifting. Bake unevenly and linewidth distribution spreads out—yield walks away. We built our infrared drying lamps to knock that variability out of the process. What matters, technically We run short-wave infrared emitters with fast-response filaments and quartz optics, dumping energy straight into the photoresist layer. The system holds wafer-level temperature uniformity within ±0.1°C across the bake field, so the thermal budget stays consistent lot to lot. Soft bake profiles repeat inside a tight window, and hard bake transitions are clean—no overshoot. Cleanroom compatibility is built in: low outgassing materials, sealed housings, and controlled airflow paths keep particle generation near zero. Why it fits OLED OLED stacks are thin, sensitive, and the schedule doesn’t forgive. The lamps cut drying and bake time while keeping the profile intact, so cycle time drops without hurting film thickness control. We focus the heat where it’s needed, not into the chamber walls, so energy use comes down. Reliability is about uptime: units run 5,000+ hours with less than 5% output drop—fewer interrupts, fewer preventive swaps. What you need to know Installation comes down to matching the lamp footprint to the track port and aligning the irradiance profile to the wafer size. Lamp output is sensitive to spacing—if the gap is outside the recommended window, uniformity suffers. Expect a short commissioning run to tune the recipe. Once it’s calibrated, the process holds steady with routine metrology checks.
