A 2°C excursion in that bake window can move critical dimension by a few nanometers, and the lot leaves the track with a defect that only shows up after development. The tool won’t warn you ahead of time. It just delivers a thermal result, and the process pays for it. We build temperature sensors for wafer tools because the thermal budget in lithography isn’t optional—it’s the line between yield and scrap. If the sensor drifts, the controller chases a false setpoint. If the response lags, the wafer sees a transient the recipe never called for. Precision, repeatability, and cleanroom compatibility aren’t buzzwords here. They’re the difference between running in spec and running with your fingers crossed.</p>
