You can’t fix it after the fact. The heater has to hold the thermal boundary conditions steady from the first wafer to the last.</p> <h3 id="what-matters-technically">What matters, technically</h3> <p>We built the CVD heater around short-wave infrared halogen elements behind quartz windows. Heat goes straight to the substrate, and wafer-level uniformity lands within ±0.1°C. The thermal profile repeats cycle after cycle, so the thermal <a href="https://o-yate.com">budget</a> stays locked. It’s compatible with cleanroom Class 1–100, and the materials and construction are chosen to keep particle generation as close to zero as possible. In practice, that means fewer contamination excursions and defect performance you can count on.</p>
