It&rsquo;s a tolerance. A 2°C excursion will shift critical dimension bias, and a handful of particles will kill a lot of good die. You need thermal control that behaves like a real process parameter, not an afterthought bolted onto the tool.</p> <h2 id="what-matters-under-the-hood">What matters under the hood</h2> <p>We build wafer-level thermal systems around repeatable uniformity and clean execution. Halogen and NIR heating architectures keep tight control across the wafer plane, holding ±0.1°C across the film during soft bake and hard bake. Quartz components and carbon-fiber-reinforced assemblies cut down on outgassing and keep the hot-zone geometry stable. That translates to consistent activation of the photoresist chemistry—predictable edge bead control, a stable glass transition, and repeatable etch selectivity. Control loops are tuned for fast settling with minimal overshoot, so you don&rsquo;t burn up thermal budget across the lot.</p>
