You need a heat source that behaves like a constant, not another variable to chase.</p> <h2 id="what-matters-technically">What matters, technically</h2> <p>We run a twin-tube, gold-coated lamp that leans on short-wave infrared, housed in a gold-coated quartz envelope. The result is fast, directional heating with <a href="https://o-yate.com">minimal</a> radiative loss. The twin-tube geometry evens out the load, which cuts down on hot spots and improves spatial uniformity across the wafer. In real terms, you get wafer-level temperature uniformity within ±0.1°C during soft bake and hard bake, and setpoint repeatability of ±0.2°C from batch to batch. The gold coating reflects infrared back into the target zone, which tightens the thermal profile and keeps <a href="https://o-yate.net">energy</a> use in check. After 5,000+ hours, the output stays stable, with less than 5% intensity drift.</p>
