We built our semiconductor laser diode heater to stop that drift where it starts, because in this business thermal control isn&rsquo;t a support system—it is the process.</p> <h2 id="infrared-precision-sub-millimeter-uniformity-repeatable"><a href="https://o-yate.com">Infrared</a> Precision: Sub-Millimeter Uniformity, Repeatable</h2> <p>We pair near-infrared (NIR) emission with low-thermal-mass wafer heating, so the thermal <a href="https://goldisgood.com">field</a> stays tight—sub-millimeter—and edge-to-center deltas shrink. Across the active zone, you get wafer-level uniformity within ±0.1°C, and repeatability that holds up shift-to-shift, lot-to-lot. The response is fast and predictable, which means soft bake and hard bake profiles stay locked to spec without overshoot. No chasing the curve.</p>
