Wafer heating has to be repeatable, clean, and quick—every cycle, every lot. No exceptions.</p> <h2 id="what-matters-under-the-hood">What matters under the hood</h2> <p>We build custom infrared heaters for wafer processing, pairing short-wave or medium-wave emitters to your thermal budget. Across the bake zone, we target wafer-level uniformity of ±0.1°C, with setpoint response under 2 seconds. The heater body is quartz and high-purity ceramics, and the joints are sealed to keep outgassing and contamination out. In Class 1–100 cleanrooms, we keep particle generation low by design. There’s no direct airflow across the hot zone, and we put in an internal particle trap geometry. Control is closed-loop, using calibrated sensors traceable to wafer-contact measurements, so your soft bake and hard bake profiles stay consistent shift after shift.</p>
