Not “close.” The setpoint. Every run. A soft bake that drifts changes resist viscosity and standing-wave behavior. A hard bake that’s not uniform leaves edge residues, shifts reflection notch depth, and turns CD control into a daily fight. When thermal uniformity is off, you stop trusting the tool. You start chasing excursions instead of running the process window. Medium wave infrared heaters were built for that constraint: repeatable temperature delivery with sub-millimeter spatial control of the heat field.</p>
