Any leftover water marks, micro-stains, or surface tension gradients will show up downstream as photoresist adhesion issues and particle defects in lithography. When the process window tightens below 2 nm, the standard spin-dry cycle just can’t keep up. The root cause is thermal.</p> <h3 id="what-actually-matters-technically">What actually matters, technically</h3> <p>We swap broad-spectrum heating for targeted <a href="https://goldisgood.com">energy</a> delivery using NIR. The wavelength is tuned to the water absorption peak, not the substrate. That gives us wafer-level thermal uniformity of ±0.1°C across the entire surface. Evaporation becomes predictable, without shocking the wafer or triggering photoresist outgassing. The platform is built for Class 1–100 cleanroom <a href="https://o-yate.net">integration</a> and runs with zero particle events during operation.</p>
