On the lithography floor, you know how it goes. A sub-1°C swing during soft bake can quietly print a line-width error that only shows up at metrology. The same thermal drift can turn wafer drying into a particle and defect problem. We built the Lab-on-a-Chip Drying Heater to stop that drift where it starts. What matters, technically The platform leans on short-wave infrared, driven by a quartz-halogen emitter array. Closed-loop pyrometry keeps wafer-level thermal uniformity at ±0.1°C across the active zone. Batch-to-batch temperature repeatability lands at ±0.2°C, so your photoresist bake profile stays locked in. It’s cleanroom-ready for Class 1–100: 316L stainless chamber surfaces, FM4910-rated materials, and a laminar airflow plenum that holds particle generation at zero during the cycle. The heater integrates SECS/GEM and runs 24/7, with MTBF over 10,000 hours, backed by an emitter life that tops 5,000 hours. Why it works where it matters This unit is aimed squarely at the lab-on-a-chip drying step—right after spin rinse, before hard bake. It dries without marring, leaves no residue, and preserves the photoresist profile you set during soft bake. That translates into fewer reworks, stable critical dimensions, and yield you can plan around. Power draw is low enough to show up on the utility line, and the footprint is tight enough to sit alongside coaters and track tools. Here is what to plan for You’ll need a dedicated 208–240 V, 16 A line. Thermal mass is low, but warm-up hits a high peak load. The chamber handles standard 150 mm and 200 mm carriers; 300 mm requires a carrier adapter kit. Installation in a cleanroom typically takes two days, with verified return-air ducting. The one trade-off: if you push setpoint ramp rates above 10°C/s, add a short stabilization dwell to keep uniformity inside spec.
