Heat can&rsquo;t be a wild card. It has to behave like a controlled process parameter.</p> <h2 id="what-matters-under-the-hood">What matters under the hood</h2> <p>We built the inspection tool heater around ±0.1°C steady-state uniformity across the stage, and that comes from a low-thermal-mass design that responds fast. Quartz or ceramic heating elements are paired with a PID loop tuned for sub-second settling, so setpoint changes track clean—no overshoot. It&rsquo;s cleanroom-compatible through and through: low-outgassing materials and sealed interfaces keep particle generation in check. The payoff is practical—repeatable soft bake and hard bake translate straight into stable lithography overlay and CD control.</p>
